Your Solar Panels at Night
To an average person, solar panels are generally known to generate power during the day. However, have you ever wondered what happens to solar panels at night or on cloudy days?
The Philippines, on average, gets about 4.5 – 5 hours of sunlight per day. This means that homes or businesses that are powered by Solar PV systems get about 18 – 20% optimal use and the remaining 80% is to be determined.
Before we take a look into how Solar PV systems work at night, we must see first how Solar PV systems generate power.
How do Solar PV Systems generate power?
In order for solar PV systems to convert solar energy into electricity, you need to have ample sunlight. This is why solar panels work best during summer months! Generally, you can still generate a little bit of power for your homes and businesses.
The great thing about solar is that the power generated by the system can be switched at any time to draw from a power grid; be used at the same time as your local utility provider; or when on an off-grid or hybrid system; used as a backup generator for your daily electrical needs.
Do Solar PV systems work at night?
If you have a battery bank set up, you’ll be able to access the stored energy your Solar PV system has generated when needed. Most Solar Homes or Solar Businesses gravitate towards getting backup-batteries as well, in case of emergency situations where power outages occur, or in some instances use the leftover generated power at night.
Even without a battery bank, solar PV systems can help heavily reduce your utility bill from the moment of energization.
When looking at investing in Solar from a financial perspective, the results of the investment is ideally captured per year and not so much on a particular day. Utility companies will usually compensate you at the end of the month for any extra power that you generate from your Solar PV system all while reducing your own cost and impact on the environment.
