Things You Need to Consider Before Installing Solar PV

Over the past few years, solar power technology has made remarkable advancements. The number of solar energy systems being installed in UK homes has seen a significant increase. By installing solar PV panels, you can reduce your environmental impact while still powering your home or business with renewable energy.

However, there are several factors you need to consider before actually going ahead with the installation. This guide will walk you through the key considerations you should make before installing your solar panel system.

Key Takeaways

• Before installing solar panels, evaluate the strength of your roof to ensure it can support the panels, and consider reinforcing it if necessary.
• Choose the right type of solar panels, as their quality directly affects your PV system's efficiency and longevity.
• Invest in a high-quality inverter, which can be a limiting factor for your solar installation and plays a crucial role in its performance.

Key Considerations Before Solar Panel Installation

With the relatively low cost of solar panels, many businesses and homes are transitioning to solar power. By decreasing grid energy use and increasing self-generated solar power, you can save money on electricity costs or even go completely off the grid.

Wondering how to install solar panels for your home or business?

A professional solar installer will handle this easily. However, you need to understand what you're doing to ensure you get an installation worth your money. Here are some factors to consider before installing a solar panel.

Roof Strength

There's a chance that the roof of certain buildings, especially older ones, isn't strong enough to hold solar panels. 'W' framed trussed roofs are common in buildings built after 1970. Solar panels typically weigh around 20 kg each, and they can easily handle the weight of many panels.

While installing cross strengtheners isn't an especially expensive process, it may be necessary for older buildings. However, every roof should be inspected as it might contain termites or woodworms, significantly undermining its structure.

Several solar firms offer free roof assessments to determine if your roof is suitable for solar panels.

Types of Solar Panels

Various solar energy systems are readily available in the market. Unlike photovoltaics, which can generate electricity, solar thermal systems can only be used to heat water.

The two most common types of solar energy systems are monocrystalline silicon panels and polycrystalline silicon panels. Although monocrystalline silicon panels have the potential to provide somewhat greater efficiency than polycrystalline, this is often outweighed by numerous other variables.

The amount of electricity your PV system produces is greatly affected by the quality of the solar panels you use. Once installed, a solar PV system runs up to almost 25 years. Thus, selecting a system from reputable solar companies will help your system run smoothly and without effort.

Inverter Requirements

Your solar PV system comprises more than just the solar panels themselves; it also includes an inverter. Getting a high-quality inverter is crucial since these devices are often the limiting element for any solar installation. In most cases, the inverter is the first gear in the configuration to need replacement.

The lifespan of an inverter is typically between 10 and 15 years. If you're having trouble deciding between spending more on a quality solar panel or a top-quality inverter, your best bet is to spend the extra money on the inverter.

Energy Use

If you choose a qualified solar installer, they will help you track your energy use. This is crucial in establishing the desired output of the solar installation. Knowing your typical energy use can help you determine the number of solar panels you should install and what percentage of your energy needs can be met by solar energy.

Financial Incentives

Those looking to set up solar panels may receive financial incentives from the government in the UK. This aims to make it possible for electricity produced by solar technology to compete on an equal footing with other types of energy generation.

These subsidies may come in a variety of different ways. The two primary types are:

• Investment subsidies are a scheme where a portion of the cost of solar panel installation is partly returned.
• Feed-in tariffs/net metering allows you to sell the solar power you create to the electrical company that operates the grid. Here, your panels are connected to the consumer unit. This helps extra energy produce a return to the grid, in turn making you money and reducing your electricity bills.

When determining if it makes financial sense or not to put solar panels on your house or company, one of the most important factors to consider is whether or not your community offers any financial incentives.

Assessing Your Needs

Fortunately, there are not many power outages in the UK. However, if you have solar panels, it is unlikely that you can rely upon them to power the house if a blackout occurs. This is because the majority of solar power systems are connected to the grid through the use of a grid-tied inverter.

You must shut the grid down for necessary repairs if a blackout occurs. Therefore, even if solar panels are a good purchase, you shouldn't count on them to rescue you in a power outage.

If you want to safeguard yourself against power outages, you must invest in a battery backup system.

Solar Battery

Since most households only use solar panels in the morning and the evening, the middle of the day—when the sun is shining brightest—doesn't always line up with peak power use. In reality, people use their TVs, air conditioners, heaters, and other home equipment the most in the evening, after the sun has set.

Therefore, economically and environmentally, charging a solar battery during the day makes sense and consuming the stored energy afterwards.

Professional Installer

Once you fully grasp the issues mentioned above, it’s time to choose a solar installer. A professional will guide you in the following ways:

• Take a look at your needs
• Guide you toward the best installation and set-up
• Make sure that proper planning permission and papers are obtained
• Ensure that installation is carried out and the necessary connections are made

Importantly, installation must be performed exclusively by trained experts. If you use a service, you may as well use one you know you can trust.
