How many solar panels do you need to run a pool?

If your pool has a total surface area of 400 square feet, 50% offset means you will need a total of 200 square feet of solar panels to heat it. As a reference; a single 4’x12. 5′ solar panel has a surface area of 50 square feet, so a system with (4) 4’x12. 5′ solar panels has a total surface area of 200 square feet.

Is solar pool heating worth it?

You can significantly reduce swimming pool heating costs by installing a solar pool heater. They’re cost competitive with both gas and heat pump pool heaters, and they have very low annual operating costs. Actually, solar pool heating is one of the most cost-effective use of solar energy in some climates.

How much do solar panels heat a pool?

Right now, an unglazed solar system can heat a pool to 78-85 degrees Fahrenheit without much effort. Solar pool heating panels last about 20 years, so in that scenario you could be looking at about 17 years of cost savings.

How long does it take for a solar panel to heat a pool?

A solar-heated pool in Southern California using unglazed solar panels will warm up to comfortable temperatures between 78° F to 85° F in just a few days in the beginning of spring, while a similarly sized pool in New York can take up to a whole week to warm up.

Are solar heated pools warm in winter?

On average your solar pool heating will increase your pool temperature by 5 – 15 degrees than it’s current temperature. Therefore, it should not be relied on to create a warm pool 365 days in the year. However, multiple factors will impact upon the temperature of your swimming pool during the winter months.

How warm should a pool be?

78 to 86 degrees Fahrenheit

According to the World Health Organization, water temperatures ranging from 78 to 86 degrees Fahrenheit are generally comfortable and safe for those engaging in moderate physical activity in a pool.

What is the most energy efficient way to heat a pool?

Using a Natural Gas or Propane Pool Heater



Gas heaters are probably the most powerful heater option. They’re very efficient and will heat your pool quickly, especially if you live where temperatures are cooler. However, it is not a cheap system to install. And you do have to pay for the gas to keep it running.

How long does it take for a pool to warm up without a heater?

Without a heater it very much depends on the weather. A number of hot sunny days or quite a few cool cloudy days, anything from two days to a month. It also very much depends on how much you want to get in the pool, ie are willing to try the pool at cooler temperatures.

Will black garbage bags heat my pool?

One way of putting this concept into practice is to float large black trash bags (yes, trash bags) in your pool. The bags will absorb heat and transfer it to the pool water, warming it up, while also serving as a barrier that prevents warm water at the surface of the pool from evaporating.

Should you keep solar cover on pool during day?

Solar Cover Use



Generally speaking, you should have the solar cover on the pool whenever the pool is not being used. During the day, having the cover on the pool helps to prevent water and chemical evaporation in the hot sun and also warms the pool.

Is it cheaper to heat a pool with gas or electric?

PoolResearch.com estimates that harnessing the energy of the sun to heat your pool only costs $10 a month or $120 annually if you warm the pool year-round. Compare that to $120-$200 a month for electric heat pump heaters and $200-$400 a month for natural gas and the upfront cost of a solar water heater isn’t so bad.

Is a pool heat pump worth it?

Heat pump pool heaters cost more than gas pool heaters, but they typically have much lower annual operating costs because of their higher efficiencies. With proper maintenance, heat pump pool heaters typically last longer than gas pool heaters. Therefore, you’ll save more money in the long run.

Can you power a pool heat pump with solar panels?

The answer is yes, it can be done; but not directly and it is typically not the best solution. Solar pool heating panels use solar thermal technology to heat pools. Solar radiation is absorbed and heat is transferred from the panels to the pool water within. This is a very simple and efficient process.
