Yes, their high reach and pressure makes cleaning large sections of solar panels much easier but doing so runs the risk of damaging the panels. So, never use a high-pressure washer to clean your panels! One of the best techniques for cleaning a solar panel is rather simple – use a brush and soapy water!

Your system should be completely shut down before cleaning as per the shutdown procedure listed in your user manual or your inverter manufacturer’s operating manual. DC Systems will need to be completely shut down. AC Systems should be shut down via the Solar Supply Main Switch.

The most effective way to clean your solar panels is with a hose and a bucket of soapy water. Essentially, in the same manner you would wash your car at home. Keep in mind that solar panels can be extremely hot when the sun is beating down on them. It’s best to pick a cool, overcast day to clean the panels.

Solar panel installation costs around $18,500 for a 6kW solar panel system for a 1,500 square ft. home and the price per watt for solar panels can range from $2.50 to $3.50. Residential solar panels are usually sized at 3kW to 8kW and can cost anywhere from $9,255 and $24,552 in total installation costs.

These panels absorb the sun’s energy in order to create direct current (DC) electricity. Additionally, solar energy cannot be used in the case of a power outage in order to protect utility repairmen working to restore power.

So the quick answer to the question of whether or not solar panels will work during a power outage is no. Solar panels will not be able to provide your home or business with electricity during a power outage.

Solar power systems will not work during a blackout for technical and safety reasons. In the hours without consistent sunlight, you’ll still receive your electricity through the traditional grid system. Similarly, the majority of solar systems work is using monitoring and inverter devices.

A hybrid solar inverter can work without batteries. This type of system is attached to solar panels and to the power grid which supplies power from both.

Therefore, utility rules mandate that in the event of a power outage, solar arrays must automatically shut down. Solar systems have detectors that sense whether power is coming across the grid, and whenever grid power is down, they automatically shut down too, to protect utility workers.
