Frequently Ask Questions

How do Solar Panels Work?

Solar panels harness the sun’s energy to generate usable electricity.

They consist of photovoltaic (PV) cells made of semiconducting materials, usually silicon, that absorb photons from the sun and release electrons. This generates an electrical current that can be utilized to power residential and commercial properties.

The inverter transforms the direct current electricity generated by the panels into the commonly used alternating current electricity for homes and businesses. The AC electricity is then sent to the electrical grid or stored in batteries for later use.

Overall, solar panels work by taking advantage of the photoelectric effect, where light is converted into electrical energy, to produce clean and renewable electricity from the sun.

What are the Benefits of Solar Panels?

Solar panels offer many benefits, including:

  • Clean and Renewable Energy Source
  • Cost Saving Investment
  • Increased Energy Independence
  • Increased Property Value
  • Low Maintenance

Solar Panels for Home

Solar panels for usage in homes refer to photovoltaic (PV) systems designed for residential properties. These systems typically consist of solar panels, an inverter, wiring and mounting hardware, and are usually installed on the roof or other suitable area of the home.

Do solar panels come with batteries?

Solar panel system do not come with batteries; however, it is possible to purchase a battery backup solution separately. While the general function of solar panels is to use the electricity as it is generated, solar batteries store the power your panels have produced during the day so you can use it later. Solar batteries are very useful in times of power outages or rainy weather and during the night time when solar panel system cannot produce electricity.

What are the different types of solar power systems?

  • On-grid solar systems
  • An on-grid or grid-tied solar system works along with the grid. This means that any excess or deficiency of power can be fed to the grid through net metering.
  • An ideal solution to reduce the bill
  • Off-grid solar systems
  • An off-grid solar system permits electricity to be harnessed by solar panels and stored inside a battery without a direct connection to the utility grid, providing an independent power supply to your home or business.
  • Ideal for power cuts
  • Hybrid solar systems
  • A hybrid solar system is when your solar panels remain connected to the grid’s power lines and have a backup battery system to store excess power.
  • while reducing the bill, this solution will save you from power cuts

Do solar panels give you free electricity

Solar panels generate electricity from daylight which is free of course and therefore cut your energy bill.  However, you are still likely to get an electricity bill with solar panels owing to a variety of factors such as battery storage efficiency, cloudy or rainy days, and so on. Even if you were to receive an electricity bill, it is guaranteed that the average cost of your electricity bill will decline upon the installation of solar panels.

What is the running cost of solar panels?

The running cost of solar panels is relatively low, as they require very little maintenance. Apart from the initial cost for the installation of the solar panels, several running costs are likely to incur during the timespan, such as solar panel maintenance and cleaning costs, and insurance for the solar panel system.

How many solar panels are needed to power a typical house?

It is estimated that a typical home requires between 8 to 12 solar panels to cover 100 percent of its electricity usage.

The actual number of panels you will need to install depends on factors including your geographic location, panel efficiency, panel-rated power and your personal energy consumption habits.
