I have a 12 V ..20 watt solar panel running a 12 v 15 watt fish pond pump ,I want to connect a battery between the two for continues running ,what would be the best size battery (amps ) and what sort of charge controller would be best ,thanks
firstly thanks for your imputs so far
when I say"continues running " I was meaning during periods of cloud through out the day instead of the stop start that happens at the moment
when it’s a very cloudy day then I don’t expect the pump to run but I want to make sure it doesn’t run the battery too low

If you are running the 15W pump continuously, the 20W solar panel won’t be big enough. 15W x 24 hours = 360 watt hours (wh). Since the solar panel is generating electricity only during sunny hours, it can’t keep up. Let’s use 5 sun hours as an example, which is the total number of hours the sunlight is equal to the standard test rated power. 20W x 5 hours = 100wh. You’re 260wh short. You need around 95W to do what you want. (360wh / 5 sun hours + ~30% inefficiencies) http://www.altestore.com/store/Solar-Panels/100-to-149-Watts-Solar-Panels/Carmanah-CTI-110-110W-12V-Solar-Panels/p6871/

For the battery, you’ll need a deep cycle battery that is designed to be drawn down to about half way and recharged, repeatedly. They are rated in amp hours, (ah), not cca. Since you only can use half the power in it, you need it twice as big as you calculate. If you need 360wh, that’s 30ah usable power, 360wh / 12v = 30ah. 30ah x 2 (only using half of battery) + 15% (battery losses) x 1.19 (50F temperature compensation)= 82ah battery. http://www.altestore.com/store/Deep-Cycle-Batteries/Batteries-Sealed-Agm/Universal-Ub12900-12V-90Ah-20Hr-Sealed-Agm-Batt/p2004/

The charge controller is rated based on the current output of the solar panel. That 110W 12V panel is rated at 7.5A. Add 25% safety margin, you need at least a 9.3A charge controller. If you get one with a low voltage disconnect (LVD), you can have the pump automatically shut down if the battery gets low, saving the life of the battery if you’ve had a day or two of clouds or rain. http://www.altestore.com/store/Charge-Controllers/Solar-Charge-Controllers/PWM-Type-Solar-Charge-Controllers/Morningstar-Charge-Controllers-PWM/Morningstar-Sunsaver-Ss-10L-10A-12V-Pwm-Chgctrl-Lvd/p799/

You can run the numbers through a calculator like this to see for yourself, http://www.altestore.com/store/calculators/off_grid_calculator/

…….Update based on asker’s update…………. If you just want to run it for as long as you can with your 20W solar panel, you can size it based on your potential output from the solar. Let’s say 1.3A output, 5 sun hours, so 6.5ah. Multiply by 2 since we’re only using half of the battery, so at least a 13ah battery, figuring you’ll be using the power about as fast as it’ll be putting into the battery, so it’s really just acting like a buffer. I suggest rounding up if possible, since I didn’t figure in any inefficiencies or losses. http://www.altestore.com/store/Deep-Cycle-Batteries/Batteries-Sealed-Agm/MK-ES17-12-18-Ah-Sealed-Lead-Acid/p5925/ . Or if budget is more important than running duration, then http://www.altestore.com/store/Deep-Cycle-Batteries/Batteries-Sealed-Agm/Universal-UB12120-12V-12AH-20HR-Sealed-AGM/p1996/.

I still recommend a charge controller with a LVD to turn the pump off when the battery is low. So, while the panel requires only about a 2A charge controller, the smallest charge controller I can think of with LVD is the 6A, http://www.altestore.com/store/Charge-Controllers/Solar-Charge-Controllers/PWM-Type-Solar-Charge-Controllers/Morningstar-Charge-Controllers-PWM/Morningstar-Sunsaver-Ss-6L-6A-12V-Pwm-Chg-Cntrl-Lvd/p804/.

Furnishing and accessorizing a deck can easily be a pleasant experience. A wide variety of different products are vailable to a homeowner. It is very important to avoid going to the extreme by placing too much on the deck.

This can easily turn the outdoor living space into an obstacle rather than a structure that enhances its aesthetic and functional qualities in relation to the home and yard.

In situations where the deck is to be used year round or during the evening, outdoor lights, fire pits and patio heaters merit consideration. Plan extra space around grills and fire pits. Take the steps required to ensure that passageways that are frequently used are a minimum of 4 feet wide and are clear of any kinds of obstruction.

Hot tubs and water features should only be considered if there is sufficient space available. Features such as these demand careful planning, substantial amounts of space, weight supports and their own electrical circuits.

Decorative lighting is a great way to establish the mood on a deck. The possibilities are almost limitless. Low voltage commercial light strings can be woven along railing systems or in nearby overhanging branches. Low voltage light fixtures can also be hidden in hanging planters to create a feeling of ambiance.

The addition of lights to the surrounding yard greatly enhances the view from the deck at night creating drama as well as a sense of security. Utilize spotlights or floodlights to accent trees, shrubs and sculpture. Add spread lights to throw light horizontally across a garden or flower bed. In addition, position wash lights to reveal texture on a surface such as a chimney or masonry wall.

Decorative lighting fixtures for the outdoors are available in both line and low voltage types. Often they are available with a choice of lamps that include halogen, incandescent and compact flourescent. The latter lamp type is energy efficient and lasts the longest.

Avoid solar powered lights because the light output they generate is quite low. LED lighting fixtures are the wave of the future for low voltage deck and landscape lighting. These lights work well on stairs, in railing systems and when mounted on railing posts.

LED bulbs have an incredible lifespan and virtually never need changing. Although LED light fixtures cost more initially than their traditional counterparts, they are cheaper in the long run. They also conserve energy and are cooler thus reducing any danger related to finger burns.

A hot tub can be a great deck addition for relaxation but it requires a good deal of planning. Details must be worked out well in advance for its size, the number and placement of water jets, the location on the deck and support. All this must be done before any concrete is poured and any framework is built.

Hot tubs come in a variety of materials that include acrylic, stainless steel and ceramic tile. They also vary greatly in size with capacities up to 8 people.

The hot tub should be located in a space that maintains privacy. A separate open air or screened gazebo can work extremely well while providing a handy place to store towels, robes, shoes and even books.

Where the hot tub is part of the main deck structure, consider the installation of built-in seating around it. Think about placing planters in such a way as to separate the hot tub from other activity areas. Hot tubs can be installed flush with the deck surface or they can sit on the deck’s surface.

Flush type hot tubs need a concrete slab for support. Hot tubs on the deck surface require extra footings and additional framing.

Any hot tub will need a water source, an electrical source, housing for the pump, valves and filter. A ground fault circuit interrupter (GFCI) is a must to prevent possible electrocution. A wise decision would be to involve a licensed electrician and plumber in the addition process of a hot tub to the deck.

Ornamental water features, either freestanding or wall mounted, can buffer unwanted noise and provide a measure of relaxation. They require a power source to operate the pump motor. Water can be added occasionally to replenish the system and help to keep the pump functioning efficiently.

In cases where the foutain has a large water basin, a direct water source and a float valve can be used to maintain the water level automatically.

Reflecting pools and small ponds are wonderful possible deck accessories. Most often they are permanent structures with poured concrete or brick bases. A pump is a necessity to keep the water aerated and prevent the growth of algae. Again, a GFCI is an absolute necessity.

The pond or pool can be lined with either a rigid or flexible liner to keep water from draining away. Stones can be place around the edges to keep the liner in place and add a natural look. A wide array of aquatic plants such as water lilies can provide many decorative opportunities for the home gardener.

The number one activity on a deck is the burning of meat. Portable grills include larger grilling areas, side tables for resting serving plates, wheels so that the grill can be moved out of the way when necessary, rotisseries and side burners.

Built-in grills are a recent popular option. The advantages of these include permanent gas hookups, large grilling areas and roasting capactitiy, optional burners and rotisseries as well as durable weatherproof construction.

Portable or permanent food preparation and staging counters are becoming more popular. The space below the counter can become a cabinet for the storage of basic cooking and serving supplies. Cabinets on locking casters can add a great deal of portability to the food preparation and serving area.

Construction of such items will require the use of exterior grade plywood, water resistant finishes and polished stone, stainless steel or pocelain tile countertop materials.

The choice of whether or not to have a fire pit on a deck hinges upon how often it will be used and whether or not local bylaws allow it. In addition fire pits take up much space, pose safety issues and can be an eyesore at times. An alternative to a fire pit might be a chimnea or a portable fireplace.

The second choice, often called a fire bowl, is generally ringed with a stone ledge which can double as a place to set down a drink or plate.

More and more homeowners are opting to extend the outdoor entertaining season on the deck by using parasol shaped patio heaters. They are movable and burn kerosene, butane, propane or natural gas. Patio heaters come in many styles, sizes and price ranges.

Safety features can include emergency cutoff valves, flame controls, electronic ignition and infrared heating technology. The best placement is in a wind sheltered area.

The final option would be a built-in masonry fireplace located near the perimeter of the deck. It can be constructed with stone or brick which can complement materials already in existence around the house and yard.

Successful deck planning should take into account furnishing and accessorizing a deck so that homeowners, family members and guests will have every opportunity to enjoy their time on this new outdoor living space.

Hello,
II have an 8 ft x 8 ft pond which is 23 inches deep. It has an 12 inch stream from 1 end that connects to a 66 inches round holes which is 23 inches deep. This latter part is the fountain. There is an underground system that circulates the water between the pond and the fountain via the stream and underground. The filter and pump are above ground.

I have 2 Koi fishes and some Goldfishes in there during the summer and fall. I would like to keep the fishes out there in the pond throughout the 4 seasons we have in Toronto, Ontario, Canada. What kind od solar system can I make to heat the pond during the cold freezing winters of ours as well as throughout the year? Would it be too hot in the summer for the fishes? I live in Toronto, Ontario, Canada – Corner property facing North_South
Currently have to bring the fishes in and am not able to do that for too long.

I would appreciate any suggetions anyone may have.
Many thanks

I don’t know of any dedicated solar pond heaters but you can go online to get solar panels/kits etc…however given the small volume of your pond( volume/water=thermal mass) and the cold temps it will take several panels in series(where will you put them?) and will be cheaper to replace the fish each year.

We are considering adding a garden to our backyard, and we understand we need a pump. The place where we want the pond is too far away from the house to be grid powered. We considered solar and wind powered pumps, but we don’t have enough sun or wind. I was wondering if there is a working perpetual machine, such as a perpetual water wheel. If so, can u send me a picture/video. THANKS!!!

Sorry, no such thing exists. You could always put in a gas powered generator but in the end you might just be better off finding a way to run AC power out to the area where the pond is to be located.

DC Digital voltmeter / ammeter

This homemade project displays output voltage and current from 2 solar panels which are used to charge batterys for a fish pond pump/filter system.

The displays appears dim on the video due to the bright background conditions, displaying 6.8V / 2.5A

I am looking to purchase one for a ~100 gallon pond and I would like it to be strong enough to make a small waterfall. Does anyone have any reccomendations on a brand?

How high is the waterfall and how many gallons per minute (gpm) do you need? If either of those answers are large, it will require an expensive pump and lots of solar panels to meet your head and flow requirements.

If you are trying to lift under 12′, and about 3gpm, the Shurflo pump might do it for you. It’s just over $100 for the pump, but then you’d need to buy the solar panel for around $500.

Some of the less expensive options you may find elsewhere may not have enough power to pump the water up for the waterfall, they may only have about 1′ or 2′ of head capability .

I am based in Thailand and therefore availability of pump types may affect this: I am building a fish pond next to the house and am thinking of using a nearby small stream to recycle the water 24/7 to remove ‘waste’ rather than put in a filtration system; the water in the stream is PH7. The stream is about 25 metres away and the head from stream to waterfall discharge point about 5 metres. My understanding is that an external pump pushing the water would be best with the overflow return by gravity. Research on the net suggests that a ‘solar’ pump would be a costly option, taking years to recover the cost, and might struggle to do the job 24/7 anyway. Any suggestions on pump type and capacity would be appreciated, balancing initial outlay with running costs and longevity at 24/7.

You are correct in your assumption about solar. The technology is not yet there for solar pumps. For the external pump you would have to place it in the stream.or get a self priming pump. There are many low wattage pumps available but I am not sure if they are available in Thailand. Below are the links to help you and make sure to look at the self priming pumps.
