Renewable Solar System

Harness the power of the sun

Solar technology has become more popular in recent years due to rising prices of traditional fuels. Increase in demand has lead to more competition in the industry and greater availability of high quality solar equipment at reasonable prices. We currently provide solar water heating equipment and installation at extremely competitive prices. Most full solar systems will come in between £2000.00 and £3000.00 inclusive of all components, installation costs and VAT. Grants for solar panels and heat panels. Most renewable technologies are available with government grants. We can help you find out if you qualify for these grants and help you apply for them so your costs are reduced even further.

What Solar Options do We Offer?

Solar Thermal Heating & Water Heating

Do away with expensive boilers with our solar thermal panels

Adding solar panels to a solid fuel heating system makes perfect sense. By using the sun to give you hot water during the summer months will mean there is no need to use expensive electric immersions or traditional gas or oil boilers. All our systems are custom designed to ensure you get the best and most efficient system possible.

Frequently Asked Questions

Solar thermal panels are typically located on the roof of a dwelling. Roofs are less likely to be shaded by anything during the day and are usually pretty close to hot water cylinders. It is always better to have panels as close as possible to the hot water storage to minimise heat loss in pipes to and from the panels. For the simplest installations the panels themselves will need to face south-east to south-west in order to catch the maximum amount of sunlight. If your house has east – west facing roof areas it is still possible to catch the sun using either a larger bank of panels on one roof or two sets of panels either side.

You will need a hot water or thermal store cylinder inside the house to store the heat generated by the panels. Many houses will already have a hot water cylinder as part of an existing hot water system. This cylinder can be replaced with a twin coil cylinder for greatest effect or reused by using various solar devices.

The solar circuit will be controlled by an electric controller usually mounted in the airing cupboard. This will detect when the panels are producing heat and transfer it to the cylinder.

The current grant scheme relating to solar thermal is the long-awaited Renewable Heat Incentive. Introduction of this scheme will happen but in two phases, with the initial tariff support available for non-domestic systems only.

The tariff for non-domestic solar thermal is 8.5p/kWh and is available only for capacities less than 200 kWth. For domestic installations, there is a one off payment available to offset the installation cost available to households meeting certain requirements.

In October 2012 the second phase will introduce a tariff-based system for domestic properties. The Green Deals scheme is also coming into place around this time which aims to help fund domestic renewable energy projects by effectively providing loans which are paid off through your energy supplier using the savings made from the renewable technologies installed. When the domestic tariffs are introduced they will be available to all eligible renewable heat installations that have taken place since 15th July 2009, although payments will not be retrospective.

There is also some money to be saved through VAT. By having your system installed by a registered installer you will be eligible for a 5% VAT rate on all components and installation instead of the normal 20% VAT. As an example this difference would equate to a £450.00 saving on a £3,000.00 installation.

We can link solar panels with combi boiler systems provided the combi boiler can accept pre-heated hot water. You will still require a hot water cylinder to store the heat from the solar panels. The hot water from the cylinder will be linked into the existing combi system using a special valve.

If you are considering doing this remember that combi boilers are actually very efficient water heaters and it may not be financially viable for you to incorporate solar thermal into the system unless you are using large amounts of hot water.

We currently source all our solar equipment from a company called Navitron. You can visit their website here for further information and advice.

We only use high quality equipment which will be expected to last in excess of 25 years. We’re not going to make and empty promises that nothing unexpected will ever go wrong with your solar equipment or installation although we do try our best to avoid complications. We will however promise to be on hand to deal with any problems as they arise.

We take our after care service very seriously and believe in treating our customers honestly and with respect. We will act as your first and only point of call if you do have problems and will take full responsibility for repairing any faults with your system in the first three years. After this period we will still be on hand for servicing and repair work and we still won’t make a charge unless we feel it’s fair to do so.

Yes you can! If you’re comfortable doing so you can purchase D.I.Y. solar kits from us or directly from Navitron. We can give any advice you may need or you can go on a training course with Navitron to learn everything you will need to know.

Remember that on D.I.Y. systems all components will be charged to you with the standard 20% VAT rate so it could be worth weighing up the options before you get stuck in!

In our area of the UK we receive a really good amount of solar energy every year. In real terms this can equate to lovely hot water during much of the spring/ summer months with an efficient and well designed solar thermal system. In the winter months you will likely need to top up your hot water in the cylinder using conventional means such as your existing boiler or electric immersion. However the solar system should still be providing as much heat as possible meaning your alternative heat source will have less work to do, reducing running costs.

Systems will be matched to your hot water usage to give you the most efficient system possible.

You will start saving money on your heating bills straight away once the equipment is installed! It’s impossible to say exactly how long the payback period is for solar equipment will be as there are so many factors that affect how much it costs to heat water in an average household as well as unpredictable rises in oil, gas and electricity prices.

If you can work out how much it costs you currently to heat your water you can get an idea of payback periods from this calculator.

At a very rough guesstimate we would say between 3 and 8 years would be average.

Solar panels are treated in the same way as roof windows which mean you currently don’t need to apply for planning permission to erect solar panels unless you live in a listed building. National park areas used to be a sticking point but recent legislation permits installations in these areas too without the need for planning.

You can get further information on planning from the Pembrokeshire county council website here.

Photo voltaic energy focused on benefiting your home

Here at Little Green Planet we are committed to taking on and developing sustainable energy resources for our customers. We offer photovoltaic cells as the best way to generate energy for your home. They work by producing direct current electricity from sunlight which can be used to power equipment or batteries. Today you can plug your new solar cells into the mains and actually sell your excess electricity back to the main power grid. Our PV cells generate sustainable renewable energy with no impact to the environment.

Frequently Asked Questions

Solar photovoltaic panels convert sunlight, the most abundant energy source on the planet directly into electricity. The equipment required for this process has no moving parts and as a result requires minimal maintenance. In addition, the electricity is generated with no emissions and no noise.

A PV cell consists of two or more thin layers of semiconducting material, most commonly silicon. When the cell is exposed to light, electrical charges are generated and this can be conducted away by metal contacts as direct current (DC). The electrical output from a single cell is small, therefore multiple cells are connected together to provide a more useful output. Cells connected in this way are encapsulated (usually behind glass) to form a weatherproof module or panel.

Multiple panels will make up a solar system capable of generating useful amounts of electricity. An inverter will convert the DC power to AC ‘grid friendly’ power. This technology has been around since the 1950’s and is very reliable. All MCS accredited panels now give guaranteed outputs for 25 year periods and should continue to produce power for long beyond this period.

Popularity of PV technology has increased dramatically in recent years due in part to the introduction of payback schemes and grants. The market is now saturated with systems and the competition has led to a dramatic fall in costs. This means an average domestic system will typically come in somewhere between £6,000 and £10,000 depending on what equipment is required.

We provide tailored pricing and specification for PV systems free of charge so please feel free to get in touch for a quote.

The electrical output of a PV cell is dependent upon the intensity of the light to which it is exposed. So PV cells will generate more electricity on bright days than when skies are overcast. However, photovoltaic’s do not need to be in direct sunlight to work, so even on overcast days a PV cell will be generating some electricity.

A typical domestic PV system of 2.1 kWp in the UK would produce around 50-60% of the annual demand of an average family household (taking the average demand to be around 10 kWh per day). However, due to the Feed In Tariff incentive, a 1kW PV system will produce enough revenue to give you a net zero electricity bill! Of course, if you put in a bigger system, you will make a healthy profit!

There are different types of solar panel technology and the size of available roof space, angle to the sun, pitch of the roof and budget will have an effect of how much solar electricity you can produce. Below is an overview of the different solar panel technology.

Technology Characteristics Appearance
Monocrystalline High efficiency and fairly expensive. Prefers high-light conditions.
Power output 850-10000 units/kWp/year
Power density = 120 Wp/m2 Charcoal or dark blue
Polycrystalline (‘multicrystalline’ or ‘thickfilm’) Lower efficiency and less expensive.
Prefers high-light conditions.
Power output 850-1000 units/kWp/year
Power density = 120 Wp/m2 Shiny and spangly blue
Amorphous (‘thinflim’) Loves low light conditions and cheap but you need a very big area to put it on.
Power output c1000 units/kWp/year
Power density = 62 Wp/m2 Dark brown or dark blue
Hybrid Combines monocrystalline and amorphous technology. High efficiency in both high and
low-light conditions.
Power output c1000 units/kWp/year
Power density = 156 Wp/m2 Charcoal

The current scheme in place for solar PV is called the FIT or Feed In Tariff incentive scheme.
The scheme was started April 2010 in the UK, intended to reward those who invest in renewable electricity generating systems.

The scheme will pay you for all the energy produced by your system (whether you use it or not) at a flat rate determined by the size of the system and the date installed. The rate of payment will be index linked so it will rise with inflation and will be guaranteed by the FIT scheme for 20 years. In addition to this you will be paid for the electricity you export to the national grid. This rate will be a lot less than the FIT payments but still add to the income. For domestic installations the energy companies will typically assume you will be exporting 50% of the energy produced so you will be paid for this amount of energy on top of the FIT payments.

Because the energy exported is not directly monitored it is in your interest to use as much of the energy being produced as possible when it is being produced in favour of using it when there is no sun. This doesn’t mean using energy wastefully, rather using high power items such as washing machines and dishwashers when it’s sunny where possible.

Click here to find out more about the FIT rates.

The money comes from the utility companies, and the cost is passed on to their customers… in other words, the people who don’t install renewable’s pay for those who do.
There’s no reason why not. The FIT can be transferred to the new owner, and they will continue to receive the incentive. Alternatively, you may decide to come to an arrangement where you retain the FIT entitlement, by agreement with the new purchaser, who will enjoy the benefits of free or low cost renewable energy. Of course, your house will be considerably more attractive to buyers, having a better energy rating, and the attraction of annual tax-free payments for the new owners.
You are no longer required to apply for planning for solar PV arrays going on roofs, even inside the National Parks. Listed buildings are the only exception to this rule. If you are considering a ground array planning permission will be required.

Solar systems are very reliable. We would however recommend a service every 3 – 5 years just to make sure everything is operating as efficiently as it can. During a service we thoroughly clean the system and check the electrical outputs. Servicing can make good financial sense as the output will directly affect your income from the system.
