1. Is my roof suitable for a photovoltaic solar system?
The most suitable for installing a household rooftop PV is a rural villa – with no shading on the roof. Observe whether there are any shades around your own roof and whether the light conditions are good.
Generally speaking, flat roofs and sloping roofs are more suitable for the installation of PV solar panels.
Flat roofs：
Photovoltaic panels on a horizontal roof, photovoltaic arrays can be installed at the best angle so as to obtain maximum power generation; the biggest advantage of installing photovoltaic power stations on flat roofs lies in heat insulation and temperature reduction, which can generally be 5~7 degrees, in the form of concrete piers + photovoltaic brackets. The investment cost is not high and the economy is relatively good.
Sloping roofs：
Sloped roof mounted photovoltaic power station is more beautiful, due to the slope of the roof, rainwater is easy to exclude, and the construction is simple and easy to maintain. This kind of roof mounted photovoltaic power station does not need to increase the bracket, calculate the angle of inclination. Installation can be laid according to the angle of inclination of the roof itself, while the installation capacity is not affected by the area, due to the slope, but also can play the effect of automatic cleaning power station.
2. Do I have the right to install solar panels: the roof has the right to be used independently
The construction of a household PV power station requires the right to use the roof independently. In rural areas where there are independent roofs, it is relatively easy for residents of villas to install them; for multi-storey or high-rise residential roofs, they are common areas and do not belong to a single household, the whole building owner has the right to use them.
3. How big can I install PV solar panels on the roof of my home and how much does it cost?
Depending on the size of your roof, a typical household roof can be fitted with 3kW-10kW of solar panels, although larger projects can be achieved if the area is larger and higher power PV modules are used. In general, a roof of about 10 square metres can be fitted with 1kW, adjusting the array and the actual layout, using high power modules, also able to do 7-8 square to do a kilowatt.

Most PV solar power station systems are quoted billing in watts, with the current market price at $3.50 – $4/watt (the current market has serious problems with price increases and specific prices are based on quotes from local installers). Therefore, if you have 100 square metres of roof at home, you can install about 10kW of photovoltaic power station, to 3.5 yuan / watt system quotation, you need to invest about 35,000 yuan.
4. What products do I need to buy to install a PV system and how do I choose?
A PV system consists of solar PV modules, PV inverters, grid-connected boxes, cables, brackets and other products, each of which requires careful brand selection. It is recommended to find a well-known local installer or brand dealer to install (call maysun solar’s official website for advice).
(Product recommendation: rooftop solar panels)
a. If the installer only has a 220V meter, then only the following 8KW home PV system can be installed, if the installer has a 380V meter, a system of 8KW or more can be installed.
b. distributed power access application form on the household number: installed 8KW below the system, the grid household number must be written 220V grid household number, installed 8KW above the system, the grid household number must be written 380V grid household number, can not be confused, otherwise the grid can not be handled.
c. If the installer only has a 220V meter and wants to install a system above 8KW, the capacity must be increased first.
