Simply divide the necessary alternating current electricity by the total wattage of solar panels. Assume a 1-ton AC requires roughly 1.2W of electricity to operate, therefore 1200w/250w = 4.8 or 5 panels. We investigated 250w panels here, however off-grid is preferable and more dependable for operating AC. If your budget allows, get 350w or even 600w panels to save energy further.
Air conditioners are expensive to run. Using less energy will help lower your costs. It's recommended that you install solar panels so they can provide all the power for your home during daylight hours when it's hot out and electricity prices are high. However, if this isn't possible then at least try to use less energy by switching off appliances when you aren't using them. This will allow some of the power to be stored in the batteries for when you need it later on. Appliances such as televisions, computers, and electric lights use a lot of energy even when they're not being used. They need to be switched on but not used for minutes or hours at a time in order to keep their batteries from dying.
Solar panels work by converting light into electricity via photovoltaic cells. They work best when there is much sunlight - so if you live in an area with good sunlight exposure, you won't need as many panels as someone who lives in a region that gets little sun.
Traditional solar panels typically produce around 250 watts per panel, with different degrees of efficiency. SunPower panels, on the other hand, are recognized to be the most efficient solar panels on the market. Divide your home's hourly wattage need (see question No. 1) by the number of solar panels you require. This will give you an indication of how many panels you need.
For example, if your home needs 500 watts of electricity hour and you have 10-kilowatt panels, you would need 50 of these panels. The VA rating of a solar panel determines what size of battery it can power for an extended period of time. A common mistake is to buy too large a panel. You should get at least as much information as possible about your household's energy usage, including any unusual peaks in demand, so you can purchase a panel that fits your needs perfectly.
It is important to note that solar panel output decreases over time due to weather conditions and temperature changes. However, this reduction in output is not significant enough to affect your overall energy consumption level.
Solar panels work by using the sun's energy to generate electricity without combustion or emission products. They work by utilizing the photovoltaic effect where light particles called photons hit the surface of the panel and create electrons which flow through the panel to turn gears or run motors. These electrons are then fed into the electrical grid just like any other form of renewable energy.
If you estimate that you'll get around 4 hours of direct sunshine per day and use 250 Watt panels, a single panel will produce approximately 4 x 250 = 1,000 Watt hours, or 1 kWh per day. So, if you want 10 kWh per day, you will require ten panels. If you want 20 kWh per day, you will require twenty panels.
In reality, you can expect closer to 12-14 hours of sunlight per day, so your required capacity is higher. Also, wind speed affects how much power your solar array will generate - the faster the wind, the less electricity they will produce. Finally, snow, rain, and other factors may reduce what time of year you actually experience direct sunlight all day long. But assuming you have average conditions, you'll need about 2.5 kilowatts of solar power after accounting for lost production due to cloud cover or darkness.
Here are some other useful numbers when thinking about how much energy your solar array will generate: One square meter of efficient solar panel produces about 100 watts of power when exposed to the sun. So, if your solar array has an area of one square meter, it will be able to generate 5 kW of power - enough to supply up to five 50-watt light bulbs with no loss from wind or other environmental factors. A larger array might be needed to supply a house or small building with energy.
