Solar PV Power – Advantages & Disadvantages

Solar PV Power – Advantages & Disadvantages

The advantages and disadvantages of Solar PV Power are pretty clear, but if you’re new to renewable energy, then it can be a little bit hard to get your head around. In this post, I’m going to break down the key reasons why you may want to make the switch youself.

Solar PV Power Advantages

  • Value – It can completely replace your current electricity source, and sunlight is free, so once you’ve paid for the investment, there’s no further electricity bills. You don’t need to worry about rising electricity prices.
  • Grants – Owners of Solar PV panels are financially rewarded for every unit of energy that they produce, via the Feed-In Tariff, when encourages the use of renewable energy sources.
  • Grants P2 – If you produce more electricity than you need, you’re rewarded again, by selling that power back to the national grid. You can effectively be paid twice for the same power.
  • Tax-free and Rising – The money earned from these grants are tax-free, and are indexed, which means that it will go up each year.
  • Environmentally Friendly – The energy produced by solar PV panels is completely clean, and will not harm the environment.
  • For any Sized Building – Because the system is modular, you only need to install as many panels as you need. So whereas a large company like Ikea will cover their roofs with panels, you may only need a small section covered.
  • Reduce Carbon Footprint – This is something that is of concern to a lot of people, because we fly and drive far more than ever now, but fortunately, using solar is a way to reduce your carbon footprint.
  • Long Lasting – There are no moving parts which will wear out and need replacing. Once they’re installed, very little maintenance is required. They last for 25 years.

Solar PV Power Disadvantages

  • Cost – Although your investment in Solar PV will end up paying for itself (and you), the initial cost can be high, especially when you consider the alternative of connecting to the grid.
  • Space – Although most houses will accomodate solar panels, smaller houses in inner cities, with smaller roofs, may not be able to accomodate the amount of panels needed to power the property.
  • Night – Solar panels only work during the day (the clue is in the name), so you will either need battery chargers for it to work at night, or power from the national grid.
  • Direction and Shelter – Solar PV works best when they’re south facing, and if this isn’t possible, then you may be receiving less power than you had hoped for. They may also be sheltered by surrounding buildings or trees, which will lessen their effectiveness.

So there we have the advantages and disadvantages of Solar PV Power, but do the advantage out weigh the disadvantages, or is it the other way round?

Well, lets have a little summary.


We know that is can be expensive to set up solar PV systems, often in the range of £6,000-8,000 for a standard home, so that is of course a hurdle for some people. And we also need to consider that some properties may be more suitable than others. If you live in a city, with a small roof, which is sheltered, then solar may not be your best choice.

If however, you do have a suitable property, want to help with your carbon footprint, and can afford the initial payment, then it would seem that solar PV is a great choice for your property.

Not only will the system begin to pay for itself, but you have the advantage of not having to worry about future electricity bills (something we would all appreciate). You will also be paid for the energy you produce, as well as the energy you contribute back to the grid (all tax-free, of course).

So although the initial payment may be high, if you can justify it, and have a suitable property, then Solar PV panels are a great source of electricity.

If you would like to know more about Solar PV, we would be more than happy to assist you with any concern you may have, and if you are looking for a local installer, that can provide good support, then please contact us.
