Quick answer: A 20KW solar system of this configuration produces about 120KWH per day from 48x355W monocrystalline panels and driven by a 20KW/28KVA inverter. Built by Mars Solar (factory since 2008), CE/ROHS certified, 25-year panel life, shipped factory-direct to 130+ countries.
Photovoltaic power generation, how to do waterproofing, or how to do if the photovoltaic roof has been made, and the water leaks.

First of all, what to do if the photovoltaic roof leaks, there is no way to remove the photovoltaic and re-waterproof, if once the water leaks, remove the photovoltaic and re-waterproof, you can imagine the loss.
Then let's talk about self-built houses, how to make the waterproof of the photovoltaic roof, the villa is actually no different from the ordinary roof, because the glazed tiles on your roof must be done, and the waterproof under the tiles should choose strong waterproof materials that are resistant to aging. Good choice of polymer. The important point is that the tile and waterproof material must be selected, otherwise the tile will crack and the waterproof layer will be damaged.
Let's talk about how to make photovoltaic waterproofing in factory buildings or flat roofs? This is very important. In general, photovoltaic must be fixed on the shelf. If it is an iron bracket, you must finish the bracket. You are doing the waterproof layer. Otherwise, you will easily see it after the waterproof layer is penetrated. Leakage.

There is also a kind of waterproof. After finishing the waterproof layer, place the cement pier on it, and then install the photovoltaic on the cement pier, so that the photovoltaic can be fixed by the weight of the cement pier. In other words, no matter how it is, the waterproof layer cannot be destroyed.
So in terms of material selection, the photovoltaic requirement is first-class waterproof. It is best to choose paint plus coiled material, and must choose products that are resistant to aging for a long time.
In summary, waterproofing is the key to doing photovoltaics, and it is necessary to control the same life span of waterproofing and photovoltaics in order to play the greatest role of photovoltaics
