Solar Electricity FAQ

The following are answers to some of the frequently asked questions about solar electricity.

Q: What is “solar power”?

A: Solar power is the energy that is generated from the sun, which are then converted into electricity.

Q: What are the different types of solar systems?

A: Monocrystalline silicon, polycrystalline silicon, building integrated photovoltaics (BIPV), and solar hot water (thermal) panels are the different types of solar systems. Q:

What size of solar system do I need?

A: Knowing the size of solar system your house may need will depend on various factors such as your average electricity usage, your house or property location, and the amount of electricity you want to come from the sun. You may use a solar power calculator to give you an estimate solar panel cost.

Q: Do I have an acceptable location for solar?

A: In most cases, yes. Solar panels perform well when facing south, that is from 9 in the morning until 3 in the afternoon. But if it’s not feasible in your location or if your only option is facing east or west side, you can still get reasonable power from the sun (about 15-20%) or you can mount the systems to be able to get more sun power.

Q: How durable are the systems and how long will it last?

A: Solar panels from a credible and accredited solar panel manufacturers goes through an intensive testing and quality control to ensure efficiency and durability. This makes the solar panels to last even up to 20 years.

Q: Will I really see a return on my investment?

A: Home solar PV investment returns are guaranteed, which is equal to approximately 14% ROI per year.

Q: What are Solar Renewable Energy Certificates?

A: Solar Renewable Energy Certificates (SRECs) are forms of renewable energy certificates that are present in countries with specific requirements for solar energy. It represents the environmental features or benefits of generated electricity from your solar power system. These forms are regularly issued to you each time your system generates 1000 kWh of electricity.

Q: Is solar energy reliable?

A: Yes, solar energy is reliable. Because solar power is renewable and infinite, it will generate solar power for as long as the sun exists.

Q: Will the panels cause leaks in my roof?

A: Integrated PV tiles or solar panels that are installed within the roof are specifically designed to work as a whole roof system, which shouldn’t be causing any leaks or any roof problems.

Q: What factors affect the design of a solar system?

A: Some factors that affect the design of a solar system are shading, the roof’s angle, the number of shade trees, and some other obstructions.

Q: What is roof orientation and what is its importance to having effective solar system?

A: Roof orientation is the direction where the roof is facing. The perfect roof should be facing south to get an optimum exposure for the entire year.

Q: Does my solar system require batteries?

A: It actually depends on the type of solar power system you have. Grid-connected solar power systems doesn’t require batteries as excess power your system generates is sent to the power grid, which will then used by other consumers (you get credit for this excess generated power). Off-grid solar PVs on the other hand would require batteries as these solar PVs wouldn’t have power without batteries.

Q: Does solar system still work when it’s cool, cloudy, or foggy?

A: Yes. Solar panels would still work fine in medium light and will still generate significant energy in the fog, or cloudy days, although generation will be reduced (same with shading from a building or a tree/s).

Q: What maintenance do solar panels require?

A: Since there are no moving parts, solar panels don’t require very intensive maintenance. Although you may need to inspect your panels for any debris or dirt that may collect on them.
