What should you  pay attention to when installing Solar Panel?

 With the increasing popularity of solar technology, its cost has approached the cost of buying a new car. Now many small partners are thinking about whether or not to install Solar Panel. What issues need to be considered before deciding whether to use this technology to save energy?

 

1. Is the roof covered?

If your roof is covered by trees most of the year, you may not have enough "sunlight" to use it. Before proceeding, the provider or you will need to evaluate this. If your roof is well oriented and has enough sunlight, make sure it is well structured. The Solar Panel now has a 20 or 25 year warranty. If your roof needs to be refurbished in the next few years, it should be maintained or replaced before installation. In this way, you do not need to spend extra time and money to reinstall Solar Panel. Please make sure that your Solar Panel does not violate any homeowners association rules that may hinder aesthetics.

 

2. Calculate power supply efficiency

The maximum installed solar capacity you need depends on your electricity consumption, so before drawing up a plan, you must first conduct an energy audit and seek efficiency improvements. To help contractors advise on the type and size of your system, collect information about your home and electricity usage.

Check your electricity bill to determine your monthly and annual electricity demand. Your usage will be expressed in kilowatt hours (kWh). Look back at each month of the past year; you may use more electricity in some months than others (for example, you run an air conditioner in the summer). The manufacturer will provide some utilities to help with this assessment. Consider any power plan changes. If you are buying an electric car, the demand for electricity may increase. If you continue to make major changes to improve the energy efficiency of your house, you may need less electricity than in the past.

 

3. Which solar energy is most meaningful?

At present, the two main solar energy technologies are photovoltaic technology, which uses battery arrays to convert sunlight into electricity; and the second is thermal energy technology, which uses sunlight to heat water or air for internal use. If your house uses a lot of energy for heating, or if you live in a place where heating fuel is expensive relative to electricity, then solar thermal energy investment may be a better balance of payments.

 

4. How to connect to the grid?

The specific details vary depending on where you live, but the principle is that every time Solar Panel is connected to the public grid, there are some issues that need to be clarified. Does the electricity supplier have suitable electricity discounts to attract you? Once connected, how and when will the power company charge the electricity generated by your solar energy to the bill to offset part of the electricity bill? Net metering is a billing mechanism. If a residential customer has a photovoltaic system on the roof, its power generation may exceed the electricity used by the household during the day. Selling the electricity that you don't use back to the grid can save electricity bills and even get some financial returns. Usually these returns are deposited into your monthly bill in the form of Credit.
