"Much starker choices-and graver consequences-in" plan, the government of distributed photovoltaic caress tilt. With centralized photovoltaic boom faded, instead, the rise of distributed photovoltaic market.
Rooftop photovoltaic power station as one of the main force of distributed photovoltaic, favored by manufacturing enterprises, the idle workshop roof to be used again. See the dividend of distributed photovoltaic market, many residents also tempted, to claim compensation with fresh, household photovoltaic power station roof is established.
Household roof photovoltaic power station construction, how to grasp the power station load bearing capacity? The roof can bear the weight of the solar power equipment is how to calculate? This is at the beginning of the power station design must be considered.
Let's illustrate: a 3 kw home solar power roof, need 150 w solar panels in 20, the weight of the solar panel is 240 kg, stents, cement square brick weighs about 210 kg, stent area of 15 square meters, with the standard to calculate the solar power equipment of roof pressure to 30 kg/square meters. Household roof bearing are usually more than 30 kg, therefore, in the above installation of photovoltaic panels is not much problem.
Roof in addition, household photovoltaic power station in power station design, but should also fully consider the roof fixed load, wind load, snow load, seismic load and so on.
Usually, professional photovoltaic enterprises or installation company will give full consideration to the above factors when power station design, user need not worry too much.
