1) Assess How Many Solar Panels You Need

To accurately determine the required number of solar panels for a specific home, it’s important to first evaluate the household's current energy consumption.
This can be done by analysing utility bills and calculating an average monthly usage in kilowatt-hours (kWh).

Why is this important?

Setting realistic goals for solar power generation will help inform the size of the installation required; considering factors such as climate, amount of sunlight and panel efficiency can all play a huge part in determining the number of solar panels required.

Finally, the physical size of available panels should be taken into account when making decisions about installation space.

Assess Your Energy Consumption

Assessing energy consumption is essential for the successful implementation of solar PV systems, as it allows for an accurate calculation of the number of panels necessary to meet energy needs.

To effectively assess energy consumption, three key aspects are considered:

  • Energy forecasting
  • Energy storage
  • Renewable sources

Energy forecasting involves determining the expected energy demand in a given time period and ensuring that sufficient capacity exists to meet this demand. While energy storage ensures that any excess power generated can be stored efficiently so that it can be used when needed.

Finally, renewable sources such as solar PV are necessary to reduce reliance on nonrenewable sources in order to move towards a more sustainable future.

By assessing these three aspects together, a reliable estimate of how much solar power will be required can be determined for the most successful installation possible.
