In daily life, although solar panels are more widely used, many people do not know much about them. Today, let’s understand some of the things you need to understand before using solar panels.
It is possible that most people do not know how to determine whether their homes are suitable for solar panels. The following three factors can be considered to make a judgment.
1.1 The amount of sunlight received by the roof: Roof sunlight can receive a lot of sunlight, if the roof is blocked by a lot of shadows, installing solar panels is not a good choice.
1.2 Roof orientation: When the roof is facing south, it can receive more sunlight.
1.3 Electricity cost: The higher the cost of electricity in the area where the customer is located, the higher the savings that can be realized by installing solar panels.
In the current field of solar panels, panels can be broadly categorized into two types: traditional monocrystalline silicon solar panels and thin-film solar panels. When the roof design contains curved surfaces and has a large curvature, it is recommended to use thin-film solar panels because thin-film solar panels can fit the curved surfaces very well. For other types of solar panels, traditional monocrystalline solar panels are mostly preferred.
Even if the location of your home is perfect for installing solar panels, don’t rush to install them just yet, depending on how much you need to spend on your daily electricity bill. If you don’t use a lot of electricity on a daily basis, you don’t really need to install solar panels. Here, it has been summarized that when the monthly electricity consumption is more than 100 kWh, it is more desirable to install solar panels.
In addition to some national incentives, the cost of installing a normal panel for a normal family is about 0.25 dollars. For an average household, the cost of installing a 3kwatt solar panel system (including 3000 watt inverter, 24v 300AH solar battery, etc.) is about $1000~1500. If you add the incentives from some countries, the cost will be even lower.
When installing solar panels, calculate the optimal tilt angle of the solar panels depending on the latitude. And you should also be careful to avoid shaded areas due to tall buildings or tall forests.
Due to the different manufacturers, the exact duration of use of each solar panel is not certain. However, according to current market research, the efficiency of solar panels decreases by about 0.5% to 0.8% per year as the usage time increases. But most solar panels can still maintain about 80% efficiency in 20~30 years.
Some of the companies that install solar panels offer energy efficiency upgrades to ensure that solar energy is maximized for savings. Some companies offer home energy audits for their customers’ homes. This includes: replacing aging appliances, fixing pipes, etc.
Depending on the type of residential roof, the specifics of installing a solar panel system are not exactly the same. However, it can be roughly divided into the following steps: planning and design, company and user licensing program, installation, inspection and energy efficiency audit, and activation for use. This series of work will consume about 3 to 6 months.
Yes. When solar panels are installed through regular channels, usually the installation company will provide a workmanship warranty for a period of time, i.e., during the workmanship warranty period the solar panels can be repaired free of charge for any non-human damage. Depending on the installation company, this period is commonly 20~30 years.
You can seek recommendations from users around you who have already installed solar panels, or you can check the reputation of the relevant installation company in the market.
