Find a Solar Panel Installer you can trust in Potters Bar.

If you’re thinking about installing a solar system in your home or property, this is probably one of the things you’d like to know before making a purchase decision. Well, you’ve come to the right place! In this post, we’re going to give you a good insight into this to help you make the best informed decision possible moving forward. Let’s take a look!

First and foremost, it must be stated that providing a short and accurate answer to this question is nearly impossible as the amount of time a solar panel will last after dark is influenced by a number of factors. These factors include the size of your solar system, the battery size as well as your power usage. As you would have imagined, batteries are charged when there is excess energy that’s being produced by your solar system but it’s not being incorporated to power your home or property. More often than not, this occurs during the sunlight’s peak periods from about 10am to 2pm.

The time it’ll take for your battery to charge is influenced by the size of your solar system in Kilowatts, the size of your battery as well as the rate in which your system is being used. Your battery can be charged in a day or two, of course unless it’s an over-sized battery for your system.

When the sun sets and your solar panels can no longer directly run your appliances via electricity generation, the battery then kicks in. You will use about 1 to 2 kW’s of power if you’re watching TV, using the oven as well as lights internet etc. in other words, even a small solar panel battery will last all night. However, the same doesn’t apply if you’re having a party with running floodlights, three fridges and air conditioner as the battery will drain a lot faster.

Are you currently weighting the possibilities of adding a solar system to your commercial building? With lots of commercial property owners in the UK using solar now, many more are gradually coming to terms with the numerous benefits they stand to derive by getting one. Therefore, if you’re thinking about adding the system to your commercial building but do not know where to start, you’ve come to the right place.

In this post, our aim is to help you calculate the number of solar panels you’ll need to power your entire commercial building. Starting from the panels, you can begin by taking into account everything that makes use of power in your commercial building to get a good idea of how many you’ll need.

• To get started, you’ll have to determine the number of watts used by your commercial building. To get this, you simply have to go through your utility bill for kilowatt-hours (kWh). This varies amongst buildings and being able to identify your daily average energy usage will assist you in getting your solar panel needs.
• Once done, you’ll also have to determine the peak sunlight hours - having in mind that the solar panels only work when under direct sunlight. Once determined, you can then multiply the figure in hours by your home’s hourly energy usage and divide by your selected solar panel’s wattage.

In general, a medium-sized commercial building making use of an average amount of electricity will require about 70 average quality solar panels so as to cover its entire electricity needs. These are, however, just averages, so yours could be more or less so getting the idea is vital here.

It’s important to get the right size solar panel system for your commercial property. Solar panels are usually installed on pitched roofs, although they can be fitted on stands on the ground if you have some unused outdoor space. The more panels you install, the more power you’ll generate, but there’s no point buying more panels than you have space for.

Solar panel system sizes are measured in kW. 4-10kW solar panel systems are usually too big for domestic properties but are ideal for smaller commercial properties. Here’s an idea of how many panels and space you’ll need for a few different system sizes:

System size, Number of panels, Area required (approximate)

4kW, 16, 23m²

6kW, 24, 35m²

8kW, 32, 46m²

10kw, 40, 58m²

Bear in mind that solar panels can’t be less than 30cm away from a roof edge, so you’ll need more space than the area that the panels take up.

How long your solar panels will last depends on their age and quality. Most modern solar panels have 20-30 year warranties, but this doesn’t mean that they’ll stop working at this point. Many will stay at a good efficiency level for up to 40 years, while others will start to decline earlier.

Asides from the fact that solar energy can be converted into electricity with the help of solar panels, there’s also another pretty cool way the sun’s power can be harnessed - solar thermal technologies. These technologies are able to convert sunlight into heat rather than power and these are in fact the very first solar energy products that were commercialized in the United Kingdom. Solar thermal panels, in a similar way to solar PVs, can help in minimizing your carbon footprint while also assisting you to save good money on your energy bills by providing the much needed coverage for your heating needs with the help of a renewable energy source that’s totally free.

Solar thermal panels provides some great benefits which is capable of making all homeowners in the UK consider installing one in their respective homes. Let’s take a closer look at these benefits.

✓ When compared to solar PV panels, they’re a more affordable heating option and also have a shorter payback period.

✓ Solar thermal panels are more efficient than PV panels due to the fact that the heat waves are able to hold more energy than sunlight and also because there’s no electricity transformation process.

✓ Solar thermal panels are able to operate in cold climates, strong wind as well as overcast weather, and make use of an energy storage system.

✓ They can help you save about 600kg of carbon dioxide emissions on an annual basis.

✓ Although most of the solar thermal panel systems come with a warranty usually within the range of 5 to 10 years, they’re able to last up to 25 years. What’s more? The require just a little maintenance, meaning the main cost you’d have to worry about is the cost of installation.

Solar cells , also referred to as photovoltaic cells (PV), absorbs energy from the sun and converts it to generate electricity. This, however, should not be confused with photovoltaic thermal cells or PVT which operates to generate heat for water in homes. Solar cells are linked electrically and also carefully organized into a large frame which is popularly called solar panels. Generally, solar cells are produced or made of silicon semi conductors which works to absorb sunlight and then turn it into electricity for use at a home. A solar panel comprises of either 60 or 72 solar cells which are electrically interconnected in series and parallel and also positioned in between glass and plastic which is then framed.

At present, solar panels incorporated for residential or domestic purposes only possesses the capacity to make use of only about 20 percent of the sunlight they’re able to absorb and convert it to electricity - also called solar efficiency. Available in the market are also a wide range of solar cell available for both industrial and commercial purposes. This type of solar panels have an efficiency rating of about 40 percent which will also automatically make them more costly than the domestic types.

One great thing about the solar industry is the fact that it keeps improving in such a way that raises both its efficiency as well as overall quality. And with further research and development, this is expected to even increase as the years go by. What’s more? As these aspects keep rising, it’s also expected that the solar panels price should be on a decrease. That way, they’ll become available to a wider range of individuals who’ll also like to save money on electricity bills and go greener.

Solar thermal panels are panels that can be used to heat your hot water. The collectors, which are either evacuated tube panels or flat plate collectors, harness heat from the sun and transfer it to a heat transfer liquid that heats up water that is stored in a hot water cylinder. You can use a boiler or immersion heater as a back-up in the winter or to heat the water up further to reach the right temperature.

Evacuated tube panels involve a bank of glass tubes mounted on the roof tiles, and while they’re usually more expensive, they’re more efficient than flat plate collectors. They’re exactly what they sound like – flat panels that can be fixed onto your roof tiles or integrated into the roof.

Having a solar thermal system will reduce your energy bills since heat from the sun is free, so you won’t have to rely on your traditional heating as much. You’ll also be doing your bit for the environment – if you have a natural gas heating system, you could save up to 295kg of CO2 every year.

Another benefit to solar thermal panels is that you might be eligible for payments through the Renewable Heat Incentive (RHI), which is a Government scheme to encourage people to take up renewable heating technologies. As long as you have your system installed by an MCS-registered installer and you meet a few other requirements, you could receive payments of up to £525 per year for seven years. And since the average solar thermal panel system costs £5,500, you could pay off over half of your system just with these payments. That’s not even considering that you could save up to £60 a year on your energy bills if you have a gas system.

Solar thermal panels work by capturing heat directly from the sun and using it to heat water. This hot water is then passed through a coil to heat the water for your central heating system. Solar thermal systems are compatible with many existing conventional boilers with hot water tanks, and can be set up to feed in to your existing heating system.
