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.

Yes – solar thermal can be used for central heating. Solar thermal panels work by collecting heat from the sun, either through evacuated tubes or flat plate collectors, and transferring that to a heat transfer liquid that heats your hot water. This can then be used to preheat your central heating.

You’ll need a hot water cylinder to store the water that your solar thermal panels heat up. It’s likely that you’ll need an immersion heater or boiler to heat the water further so you can use it for your central heating, and as a back-up during the longest winter months since the solar panels won’t be able to generate as much heat.

In our opinion, it’s best to use your solar thermal panels for hot water rather than your central heating. That’s because you use hot water all year round, whereas you probably won’t have your central heating on in the spring and summer, when the panels can generate the most heat. For central heating, air- or ground-source heat pumps are a great renewable option, and you can even power them with electricity from solar PV panels if you want to be as eco-friendly as possible.

To have your solar panels working at full strength at all times is crucial as this can go a long way to help you reduce your energy bill. In order to achieve this, you simply can’t afford to ignore having them regularly cleaned and free from all sorts of dirt, dust, debris, pollen, bird droppings and the likes. Now it’s quite reasonable to think rain or wind should be able to get the job done, but unfortunately this is not so. What solar panels need is a proper clean which you can decide to do by yourself or call in a qualified professional – the latter which is strongly recommended.

Cleaning of solar panels has to do with working at heights which can be very dangerous especially if you don’t have enough confidence to pull it off. And even if you have zero phobia for heights, solar panel cleaning requires experience as well as some specialized skills and tools possessed by the professionals. However, the question here is, how often should solar panels be cleaned to keep them operating at optimal efficiency?

Well, according to the manufacturers, solar panels should be cleaned twice a year. However, if this is something that you feel is not achievable by you, then you should at least give then an annual clean. The best or most advisable time to do this during the year is at the end of the summer months. This will ensure that you have a fully functioning solar array which is ready and prepared to withstand whatever the cold period throws at you. At the end of the day, you’d have them looking spotless clean while also working at full strength and reducing your energy bills.

After making the very important business decision to go solar, you may also want to know just how long it’ll take to complete the installation process and start generating electricity. After all, generating electricity is the main reason you made the switch to solar system. In this post, we’re going to provide you with in depth details on how long it takes to install solar panels as well as the factors that may affect that time.

The entire process of solar panels installation and getting them approved isn’t an overnight process. You’ll have to wait for periods for each step of the process whereby one must be completed before moving to the next. The time required to complete each step can, however, vary largely depending on your location, the type of solar panels you opt for, the solar company you hire as well as the number of people that’ll be making the installation. Here are the steps to a solar system installation and the estimated time each are expected to take:

• Site assessment. Once you chosen your solar company, the first step would be to have a solar professional from the company to visit the site to examine the roof and other features so as to make sure that they’re able to support a solar system. From the initial contact to scheduling the site visit, this step can take up to 1 to 2 weeks
• Local permitting. This involves getting the right permits from your local authorities. This can take up to 3 to 6 or more weeks.
• Solar system design. This may take up to a week or two depending on whether or not you need design approval and also where the parts are coming from
• Installation. This step can take a week or two depending on the size af your solar panel and roof.
• Inspection. This step can take up to a week depending on where you reside and how quickly the inspector can visit.
• Utility connection. Depending on your utility company, this step can take up to 2 weeks.

If you’re thinking about getting a solar thermal system for your home, it’s normal to consider the possibility of using the system for central heating. So is this viable? In this article, you’ll learn how solar thermal panels can be incorporated for heating. Let’s have a closer look!

Heating and hot water systems, on the average, takes up a sizeable part ( up to 70 percent) of our energy bills. Now take a moment to imagine how cool it’ll be to generate your own hot water for free without having to depend on any supplier which in turn significantly reduces your energy bills. Well, this is exactly the work of central heating systems that are powered by solar. That’s super cool, right? Well, let’s have a look at how this works.

While solar panels generates electricity, solar thermal panels produces heat for hot water production. However, what’s important is the fact that they both make use of the sun’s natural energy to provide us with a free and renewable energy we can use in our homes. Here’s how it works.

Solar thermal panels directed at central heating incorporates the sun’s natural energy to heat water in a storage cylinder which is then available for use at home. These solar thermal panels are exposed to the sunlight by fitting them on the roof of the home. Generally, they’ll include tubes that contains liquid whose job is to collect the heat and then transfer it to a hot water cylinder that’s solar compatible in your home. The heat is generated for free and is also renewable. This is help you save lots of money on oil, gas and even electricity which you purchase to power the cylinder.

When you’re about to transform from the standard electricity to solar energy, what determines your solar system’s size is the amount of solar that’s required. The amount of solar that you’ll need, on the other hand, requires considering the end goal, be it to increase money savings, reduce environmental contamination, maximize Returns On Investment ( ROI), or just to copy what the neighbour’s done.

In order the determine the number of solar panels that is needed, the first step would be to calculate the number of kWhs that’s currently being used. A kWh is what’s used to determine the amount of energy that has been incorporated over time which the utility uses to bill you. What’s strongly recommended to create a suitable range is a 6 to 12 months average of your household electricity bill. Other factors that can play a key role in the determination of the number of solar panel needed include the following:

✓ Sunlight exposure hours. In order to know just how much energy your solar panels will generate, there’s a need to know the number of direct sunlight hours you should expect on a daily basis. For example if you stay in a region that’s usually very sunny, then it’ll be reasonable to expect more energy production per panel than regions that are usually cloudy.

✓ Angle and size of the roof. Roofs with a lot of workable space may require to let go of some efficiency opting for larger and cost effective panels to achieve the targeted energy. However not all homeowners have sufficient roof space or shade coverage for the solar panel they actually want. Also, the degree at which the roof slants will also determine if the sunlight is hitting the panels well enough and the amount of energy that can be generated thereof.
