What Are Solar Panels?

A solar panel helps convert the sun’s radiation into electricity. It functions based on the photovoltaic effect. That is, when direct sunlight touches the panel, the sun’s energy gets absorbed by the solar collectors or cells.

These cells then vibrate and help in generating electricity. This brings us to the most debated question – Why do you need a solar heating system?

What Is the Need for Solar Panels?

The environmental concerns around us are why we should start using solar power. Other than that, our traditional power source is derived from limited sources. So, it is wise to shift to solar systems.

A solar panel system is your one-time investment and is a free power source. This way, you save money and reduce energy costs.

Are you wondering whether to choose solar tube collectors or solar panels? Well, solar panels are a clear winner with a better efficiency rate.

Benefits of A Solar Panel System

Types of Solar Panels for Heating

The solar energy sector has been rapidly developing over the years. It has been adapting and producing newer varieties based on the increasing demand and choices. This has led to the creation of multiple types of panels.

The system terms and complicated types could be overwhelming. So here is a brief explanation of different types of panels.

Understanding Solar PV & Thermal

The first step in getting to know the varieties of solar panels is learning to differentiate solar PV and solar thermal. The absorbed energy from the sun is used in different ways.

If you want to generate electricity, opt for solar PV panels. And go for a thermal panel if you produce heat, and use a solar hot water cylinder. Here’s why.

Solar Thermal

The solar thermal system is used to generate heat and get warm water. If you are looking for solar water heating systems, then choosing a solar thermal system is better. It heat pumps the round liquid due to the sun and helps get a hot water tank.

Simply, it absorbs the sun’s energy to heat your household water. The installation of the thermal panel and PV panel is the same. You place it on the roof and help it get maximum heat from the sun.

The solar heating system works so that the heat generated from the panel gives warm water. It is then stored in a hot water cylinder. Whenever there is a need, the heat water stored is used.

Solar PV

Solar photovoltaics is commonly known as solar PV panels. It is used to generate electricity. Using direct sunlight, solar PV panels produce electricity and pass it to the functioning of electrical appliances at home.

Since solar PV panels produce electricity, there is always confusion about using them for hot water.

Technically, solar PV does not just reduce the costs of electricity but also helps you get free water. The electricity generated using solar PV can be used to heat your hot water cylinder.

Immersion Heater for Heating

If you have an existing cylinder with an immersion heater, you could easily use solar-generated electricity to boil water. Diverting the electricity to your immersion heater can be done using a solar power diverter.

An immersion heater is a heating element in your hot water cylinder that uses electricity to heat hot water. So, what’s a solar power diverter? On many occasions, your solar PV panel might produce excess electricity.

In such situations, a solar power diverter will divert the excess energy to the immersion heater in your hot water cylinder. Say you turn on your kettle to heat water; when the immersion heater gets the electricity, the diverter will redirect that electricity to your heating system.

Photovoltaic Thermal Collectors

The right mix of the best in both solar PV and solar thermal panels is solar photovoltaic thermals. These are also called Photovoltaic Thermal Collectors or hybrid solar collectors. This hybrid panel uses energy from the sun to produce electricity and heat.

Hybrid Solar Collectors produce a better overall efficiency than solar PV or solar thermal panels.

Heat Pumps

Heat Pumps are an integration of solar thermal panels and heat pump technology. It is commonly known as a Solar-Assisted Heat Pump (SAHP). Solar thermal panels produce the heat to feed the heat pump. Then, using a heat exchanger, the pump heats the water in your existing cylinder.

Investing in a Solar Water Heating System

There is no rule of ‘one size fits all when it comes to solar water heating systems.’ This is where it gets tricky. All the panels are equally equipped and are better in one or the other aspect. So, when you choose a panel, choose one that fits your needs.

Here are a few tips that will come in handy:

Glass

Check the kind of glass used. It is always said that tempered or strengthened glass, though expensive, is the better choice.

Size

Analyse how much power your house needs and measure the size of your roof.

Budget

The market offers both cheap and expensive panels. The costs vary depending on the efficiency and lifespan of the panel. So choose one that your budget can cover.

Climatic Conditions

Examine your place’s climatic and weather conditions before deciding on a panel.

Aesthetics

When compared, some types are more visually pleasing than others. If you want something aesthetic, buy one that looks appealing to you.

While focusing more on buying the right panel, do not forget that the system’s longevity lies in proper maintenance checks.

Pro tip

It is said that a panel placed in the south-facing roof produces the most power, so plan accordingly.

Is Planning Permission Mandatory for Your Solar Panel?

Planning permission is necessary only in some situations. Fortunately, it mainly falls within the permitted development rules.

The permitted development rules for panels include –

• They should not protrude above 150 mm of the roof.
• They should not be facing the road.
• They should not be more than the highest part of the roof (The highest part of the roof excluding the chimney).
• Other such rules.

Remember that the rules to obtain planning permission differ for properties in the conservation area.
