Are you interested in using GREEN, free energy to power your household? If so, one of the basic requirements you need to keep track of is how many solar panels you need. To determine the appropriate number of solar panels, conduct an extensive analysis of the total energy consumption of your household, the different types of solar panels available, and the amount of money you can spend on it.
DETERMINING HOW MANY SOLAR PANELS YOU NEED
Calculating Energy Consumption
When it comes to determining how many solar panels you need, it is imperative you measure the amount of energy produced by a solar panel and compare it with your overall household electricity consumption. Generally, a $300 solar panel of excellent quality can deliver approximately 100 to 200 watts of energy. Considering that the average household consumes 8000 to 9000 kW⋅h yearly, the number of panels you need for powering your entire home could be quite substantial. However, depending on your needs, you may not need to purchase many (especially if you are an environmental enthusiast who knows how to use appliances that consume less energy and provide better functionality).
Different Solar Panel Types
The efficiency and rate at which the solar cells can perform also plays a vital role in helping you determine the exact number of solar panels you need. For instance, if you are interested in solar panels that use cells made from mono-crystalline, you may require fewer panels than those built from polycrystalline or film cells. So, before determining how many solar panels you need, consider the type of panels (film, polycrystalline, or mono-crystalline) you want to have installed. This ensures you receive maximum efficiency and power.
Last, but not the least, when it comes to installing a solar energy system, you have two options: either buy solar panels from a renowned retailer or hire a company to manufacture the solar panels. DIY solar panels will obviously be cheaper. However, they may lack the quality that retail solar panels may have. Where retail solar panels may offer more electricity even in limited sunlight, DIY panels may struggle to do so. By using simple math, you can determine how many of these panels you need exactly to meet your target.
