If you’ve made up your mind to go solar and look forward to introducing photovoltaic panels into your home, there are a number of factors you should consider. If you’re still considering whether to install solar panels, read our basic introduction to solar power. Here’s our quick guide to factors to consider when installing solar power for your home.
These include your electricity needs, the amount of sunlight your home gets, the size and location of future solar panels, variables of the PV system, and the type of PV cable conductors.
Before choosing a solar power source for your home, you should consider the amount of electricity your home uses. Generally, the more electricity you use, the more panels you need. If you use a lot of electricity, you need more panels, and they should be more efficient than the average panels on the market.
Calculate the wattage your home is currently using, taking into account the size of your home and all places where electricity is used, as well as the number of appliances in your home. Before installing PV panels, you may need a professional to analyze your electricity usage, as some factors you haven’t considered can lead to excessive electricity usage.
Another key factor is the amount of sunlight your house gets throughout the calendar year.
The first thing to consider is the overall climate of the area and the amount of sunshine per day. When it comes to climate, sun exposure is the most important factor, while temperature is a secondary factor.
In fact, despite the stereotype, cold temperatures benefit solar panels because they work more efficiently and produce more electricity when it’s cold. The ability of photovoltaic panels to generate voltage decreases with increasing temperature. So cold climates with plenty of sunshine every year are ideal for solar panels to work hard.
Although not very efficient, solar panels can actually be made suitable for any type of climate. Many people choose to install solar panels in rainy, cloudy climates because it is still effective from a cost balance and sustainability perspective.
The solar energy conversion rate of high-quality PV products is significantly higher than that of inferior products. The power generation efficiency of monocrystalline modules and polycrystalline modules may be different, and generally monocrystalline is superior.
Data introduction, temperature rise 1 ℃, crystalline silicon photovoltaic module group large output power drop 0.04%.
So to avoid the influence of temperature on power generation, keep the formation of good ventilation conditions.
The panel of crystalline silicon module is tempered glass and with long-term exposure to the air, there will naturally be organic matter and a lot of dust accumulation.
The dust on the surface will block the light, which will reduce the output efficiency of the module and directly affect power generation.
At the same time, it may also cause the "hot spot" effect of the module, resulting in module damage.
Therefore, it is necessary to scrub the modules regularly, and it is recommended to use a clean soft towel to prevent the modules from being scrubbed regularly.
There are many factors you should take into account, and even the smallest details can be important. This includes the number and location of surrounding buildings, whether there are enough trees in the area, and landscaping, such as whether your house is on a hill or level ground. If your home is in a damp and humid area, don't choose PV wires with aluminum conductors.
As society moves towards reducing fossil fuels, more and more businesses and households are expected to use solar energy in the coming years. Solar energy is abundant, reliable, and good for the environment. If you don’t use solar today, ten years from now you may be the last person in your neighborhood to make this transition.
