What Size of Solar Panel Do I Need for My Home: A Quick Guide to Get Started.


The sun\’s rays are a renewable source of energy. And, if you\’re looking for ways to save money and be more environmentally friendly, installing solar panels on your home is the perfect way to do both. The first step in getting started with this project is determining the solar panel size that will work best for your home. In this blog post, we\’ll walk you through what information you need and how to calculate how many watts of power a new system can provide.

So, you have decided to get a solar panel for your home. You are so excited to make this investment and save money in the long run but don\’t know which size of solar panel you will need. This blog post will give you a quick guide on how to decide what size of solar panel will work best for your home and where you should purchase it from!

How much solar power And Size of Solar Panel will you need?

To determine how many solar panels you need for your home, first look at past utility bills. Next, you can calculate the amount of energy that will be required by multiplying an hourly requirement with peak sunlight hours and dividing it by a panel\’s wattage (ex: 17-42 to generate 11,000 kWh/year). Factors such as roof size or battery storage may also play into this calculation. If you work with SunPower experts, they\’ll handle all these calculations for you!

How many watts do you currently use?

Look at your electricity bill and find the Kilowatt Hours (or kWh) Used. Look for days represented in it, usually 30 calendar days. If you want to see daily or hourly usage, divide monthly average by 365 or annual average by 31560 respectively and then again with 24 hours of a day into an hour\’s worth of power consumption

Look on your electric company\’s website using their online portal for information about kilowatts. We use per month/year as well as how many kWh is considered one unit–we can measure electricity in either unit such that it is equal to 1000 watts (.1kW), 1 kW (1000 W), 10 kW(10 000w). So make sure when estimating usage.

How many hours of sunlight can you expect in your area?

The Renewable Resource Data Center provides sunlight information by state and for major cities. For example, if you live in Phoenix, you can expect a greater number of peak sunlight hours than if you lived in Seattle. That doesn\’t mean that the homeowner located in Seattle cannot go solar. It just means they would need more panels or less usage throughout the day due to having fewer sun-hours during their time zone\’s summer months. There are long days with increased intensity from midday through sunset because the light reflects off water on land masses around them from space (clouds permitting).

What is the effect of Size of Solar Panel?

If you want to make the most power with a limited roof area, or if it\’s best to invest in fewer high-efficiency solar panels. Larger solar panel sizes and numbers can be more expensive per unit of energy generated than smaller ones depending on how much space is available for installation.

We must consider all factors related to efficiency when deciding what size and number of residential photovoltaic cells will work well for you; this includes dimensions and shading from nearby structures and weather patterns where your house sits!
