At present, the household solar power generation system is not a necessity of life, so whether to install it depends entirely on the owner's personal will.

At a time when the cost of photovoltaic systems is steadily declining, families with enough budget of solar panel cost ontario can consider installing a set. Although the subsidies of the state are declining, it is even possible that after 2021, the subsidies of household photovoltaic systems will be completely eliminated. The photovoltaic system can still rely on its own power generation, obtain stable income, and the investment payback period is too long (considering that there are a variety of sales models for household photovoltaic systems, the investment payback period is different, and the small solid is not listed here. It should be possible to control it for up to eight years, and it does not require any investment in the initial installation of the system.)

The key to this problem is what are the advantages and disadvantages of rooftop solar panels, if the advantages outweigh the disadvantages, of course, you can install, on the contrary, there is no need!

So let's first look at the advantages of rooftop solar panels:

(1) can effectively use solar energy resources for power generation, achieve self-sufficiency, reduce household electricity expenses;

(2) In addition to meeting the basic electricity needs of households, the excess power generation can also be incorporated into the national grid in exchange for income, and the maintenance cost is very low, and after the initial investment cost is returned, the following two decades are pure income;

(3) To enhance the aesthetics of the building, the use of "roof tiles" instead of the original roof of the building tiles, reduce construction costs and achieve waterproof and sunshade effect, integrated with the building, beautiful and unique appearance;

(4) The photovoltaic roof has little environmental pollution and can reduce a lot of carbon dioxide;

(5) Installation is relatively simple and easy to operate; Generally speaking, a few workers can be installed in half a day.

Take a look at the disadvantages of rooftop solar panels:

(1) Relatively speaking, the investment is still relatively large, the installation cost is high, the short-term income is not high, and the return cycle is relatively long;

(2) Solar panels are directly installed on the roof, and there may be corrosion problems after wind and sun exposure, and later maintenance costs are higher;

(3) Solar panels can use solar energy resources to generate electricity, so they can be used in sunny days, but in cloudy days or when the sun is not particularly sufficient, the power generation efficiency will be greatly reduced, and electricity consumption will be affected.

(4) When installing, it is also necessary to punch holes on the roof, to penetrate the roof, and the later installation is unreasonable, which will cause leakage problems on the roof.

To sum up, whether it is necessary to install solar panels at home, you can refer to the above advantages and disadvantages to make a comprehensive consideration, after all, it is the best for yourself!
