Best Solar Panels for Your Home | The Home Depot

When selecting panels for your abode, its likely youll agonize over two or three apparently identical PV modules. Same efficiencies, almost identical temperature coefficients, and all the other goodies. So, whats left to make the final cut?

Money, of course.

Just like you need to compare unit prices at the grocery store for a fair comparison, look at the price per watt. For this, divide the panels price by its power rating.

Do You Really Save Money With Solar Panels

Even with todays technology, solar panels and their installation require a long time to recoup the cost of a large solar energy system. It can take up to 25 years. However, single solar panels that are used for RVs, boats or camping quickly pay for themselves by replacing expensive gasoline powered generators. Their steady charge helps expensive batteries last longer too.

Panel Size Vs Efficiency

Panel efficiency is calculated by the power rating divided by the total panel area, so just having a larger size panel does not always equate to higher efficiency. However, larger panels using larger size cells increases the cell surface area which does boost overall efficiency.

Most common residential panels still use the standard 6 square 60-cell panels while commercial systems use the larger format 72 cell panels. However, as explained below, a new industry trend emerged in 2020 towards much larger panel sizes built around new larger size cells which increased panel efficiency and boosted power output up to an impressive 600W.

Are There Grants For Solar Panels In The Uk

In the UK, you can earn money on your solar panels through various solar panel funding opportunities. Currently, there is the Smart Export Guarantee and the Feed-in Tariff .

The Feed-in Tariff was one of the governmental solar panel grants that encouraged the use of renewable energy in the UK, and solar PV was one of them. It was introduced in 2010 and offered a tariff to homeowners that generated and exported renewable energy.

In 2019, the government closed this scheme. Those that are currently still registered under the FIT continue to receive the payments as per their agreement, but no new applications are accepted.

Since the 1st of January 2020, the Smart Export Guarantee has effectively replaced the FIT. With the SEG, UK homeowners can earn money by exporting surplus energy back to the grid.

The SEG requires that all energy suppliers with over 150,000 customers must offer a tariff for electricity sold to the grid. Individual energy suppliers have a lot of flexibility in how they want to set up the tariff, but it has to be above zero. A good export tariff is 4-6p/kWh.

Another option for solar panel funding is the new VAT reduction on energy-saving products. If you are over 60 years of age, or are on income- or disability benefits, you are eligible for a price reduction on your solar panels. There are specific eligibility criteria, which you can read on the government’s website.

How Solar Panels Work

First, how do solar panels work? Solar panels are made of photovoltaic cells. The sun emits solar radiation, which is absorbed by the PV cells when the sun shines directly on them. The energy from the sun creates electric charges, which move according to the electrical field in the cell, directing the flow of electrical energy. Parts of the solar panel also convert energy from direct current to alternating current so it can be used in homes. Certain solar panel array components also store the energy for later use even when the sun is not up. You can learn more about how solar panels work in our guide.

Solar Panel Performance And Product Warranty

Are Solar Panels Worth It and Do They Really Save You ...

One of the most important criteria to consider is what warranty is provided by the manufacturer. As with most products the length of included warranty is a very good indicator of quality and durability.

Solar panels come with a performance warranty and a product warranty. The performance warranty guarantees the solar panel will still produce a minimum percentage of its nameplate output at the end of its expected life . Solar panels output always gradually degrade over time, but the rate at which they do so depends on the solar panel quality.

A solar panel product warranty covers defects in the manufacturing process. Typically in the industry we see a minimum of 10 years provided as a product warranty.

All of the companies in our top 10 list have an office in Australia who you can contact to claim warranty. This is important to ensure you have some options if your installer goes out of business.

Most Efficient Solar Cells

The most efficient solar panels on the market generally use either N-type monocrystalline silicon cells or the another highly efficient N-type variation, heterojunction cells. Most other manufacturers currently use the more common P-type mono-PERC cells however, several large volume manufacturers, including JinkoSolar, Longi Solar and Trina, are now starting to shift to the more efficient N-type cells.

Solar Panel Shopping Checklist

In summary, these are the major points you should bear in mind when buying solar panels aside from cost:

  • Consider how the module is manufactured and the materials used.
  • Carefully research how the panels perform in real world situations. This includes positive tolerance, temperature co-efficient rating, PID and LID resistance and efficiency.
  • Compare the warranty details of the solar panels you are considering buying.

    The Power Temperature Coefficient

    Higher or lower cell temperature will either reduce or increase the power output by a specific amount for every degree above or below 25°C . This is known as the power temperature coefficient which is measured in %/°C. Monocrystalline panels have an average temperature coefficient of -0.38% /°C, while polycrystalline panels are slightly higher at -0.40% /°C. Monocrystalline IBC cells have a much better temperature coefficient of around -0.30%/°C while the best performing cells at high temperatures are HJT cells which are as low as -0.25% /°C.

    Power output vs Temperature chart shows reduced efficiency at higher cell temperatures and increased efficiency at lower cell temperatures – Image credit LG.

    Power temperature coefficient is measured in % per °C – Lower is more efficient

    • Polycrystalline cells – 0.39 to 0.43 % /°C

    • Monocrystalline cells – 0.35 to 0.40 % /°C

    • Monocrystalline IBC cells – 0.28 to 0.31 % /°C

    • Monocrystalline HJT cells – 0.25 to 0.27 % /°C

    Generally cell temperature is 20-30°C higher than the ambient air temperature which equates to approximately 8-12% reduction in power output. Note, cell temperature can rise as high as 80°C when mounted on a dark coloured rooftop during very hot 40+°C, windless days.
