I've heard that solar panels have back-up batteries for when it is cloudy or rainy that day.. is this true?
depending whether the solar array is back to grid or stand alone. Back to grid refers to the array being connect through the inverter to the main electricity supply grid. So when you are producing electricity from the solar array it feeds back into the main grid. Now if you are using more electricity than your array is producing then none will feed into the grid. The stand alone systems require batteries, which are charged from the electricity produced by the solar array. Solar arrays produce electricity on cloudy and rainy days but at a greatly reduced rate ; therefore little to no usable electricity is produced. Stand alone systems require batteries to store the electricity for use at night time and other times when the array is not producing . The back to grid systems require little to no maintenance as the electricity produced is fed back into the electricity network and stored there. Your meter is replaced with a dual meter . It reads your usage and your production. If in Australia you will get paid for the electricity you feed back into the grid. hope this helps.
A PV array produces electricity whenever the sun shines on it. This is true from sunrise until sunset, and often times even after the sun sets! (A full moon on a clear night can actually produce small amounts of current from a PV system.) Generally speaking, an array will produce its maximum power between roughly 9:00am and 3:00pm.
Yes, they work but if it's real rainy they won't work as well. I don't know much about Solar Panels but I do have them in my home, and they work amazing! Once in a while if it's pouring rain, they won't work AS well but still work! I If you really want a good answer, the company I used was actually very helpful and knowledgeable. I'm sure they wouldn't mind to answer some q's! If your interested -- 866-276-7222
There okorder / Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
