Residential Solar System Designs: 3 Mistakes and How to Avoid Them

If you are thinking about making the switch to solar power, you will be joining a growing number of households benefiting from significant energy savings. You will also be playing your part in protecting the planet and lowering your household’s carbon footprint. There are currently more than 3.4 million solar energy systems in the United States, a number that is growing rapidly.

When planning residential solar system designs, it’s important to be aware of the most common mistakes. Avoiding these can help you get the most bang for your buck and a solar energy system that works for you and your household. Let’s take a look at 3 common mistakes people make when designing solar panels.

1. Choosing the Cheapest Option

The cost of installing a solar energy system in the US has fallen by around 50% in the past decade. Even if you are cost-conscious, we recommend that you pay a little more upfront and opt for a good quality system.

A Tier 1 system has a lower annual degradation rate, meaning it will generate a greater amount of electricity over the course of its lifespan compared to Tier 2 or Tier 3 systems.

Given that solar panels can last for upwards of 40 or 50 years with good care, it’s worth paying more on Day 1.

2. Choosing the Solar Panel Sizing

It is an error to buy a solar panel system that is not sufficiently large enough to meet your home’s energy needs. Similarly, having a solar system that is overly large for your household’s needs will unnecessarily increase the upfront cost.

The factors that you should consider when choosing a solar system size include:

  • The size of your property
  • Your property’s energy usage
  • The location of your property
  • The number of occupants

Partnering with a reputable solar panel installation company will help to ensure that you choose a system size that is right for your home.

3. Installing Solar Panels in the Wrong Direction

For maximum output, it is recommended that solar panels in the United States are installed in a south-facing direction. Installing solar panels in anything other than a ‘true’ south direction will reduce the output of your system.

Where possible, avoid installing solar panels in a north-facing direction, as this will incur the greatest loss of output (upwards of 30%). For many households, the most convenient place to install solar panels will be on their homes’ roofs.

Residential Solar System Designs: Common Mistakes

Installing a home solar system is a wonderful way to gain independence from the grid and reduce the cost of your monthly energy bills. It is also a way to boost property value and protect the environment. The above information will help you to avoid making the common mistakes that people make when switching to solar.
