Tips to make the electricity meter run faster and increase the power generation of the photovoltaic system!

If an industry can only survive by relying on government subsidies, then this industry will never grow. The photovoltaic subsidies will decrease year by year until they are completely cancelled. It is the general trend for photovoltaic power generation to achieve grid parity. Only in this way can the photovoltaic industry move forward. In the era of subsidies based on power generation, how to make the meter turn faster and increase investment returns, there are actually many tips. With the same investment and the same light, a little attention during design and installation may lead to completely different results. The author has tracked more than 1,000 distributed photovoltaic power stations in China and summarized some experiences to share with you.

Modules facing south, inverter facing north:

The components should face the sun as much as possible, with the angle and direction of maximum radiation. The installation angle is generally the local latitude plus 5 degrees, and the installation angle is generally slightly west of due south. The inverter is just the opposite, try to install it on the south wall, and the inverter panel should face north to avoid sunlight.

(1) The machine should be installed at a suitable height from the ground to facilitate observation and reading of the LED display.

(2) When installed outdoors, a rainproof and sunproof canopy should be installed on the inverter to avoid direct sunlight and rain. The inverter should not be directly exposed to the sun or other heat sources.

(3) Sufficient space should be left for installing and moving the inverter. For inverters below 20KW, at least 50cm of space should be left around them. For inverters above 30KW, air is drawn from the side, so more than 100cm of space should be left on both sides.

(4) It must have sufficient load-bearing capacity, which should be at least 1.5 times the weight of the inverter.
