How electricians are supporting homeowners with solar

Solar is a sustainable and clean energy source
Ask any scientist and they will tell you the 'sun' is an incredible source of energy and with the right technology and connected devices it can provide one of the cleanest and effective renewable sources of energy available. The energy available from the Sun will last sustainably longer relative to human needs than fossil fuels or other less clean and hard to source natural resources. An interesting fact, the energy the sun releases in one hour has the capacity to meet the earth’s global energy demands for one year.
What has caused the shift in homeowners thinking to solar
As homeowners become more aware of the finite nature of fossil fuels like coal, and how it contributes to the increase in carbon in the atmosphere, as well as climate change. They are looking at alternative forms of sustainable and less harmful energy sources. In the developed world asking if there is more that can be done to switch to using alternative natural energy sources, is begin to become more prevalent as a narrative, their is concern for the world, the future of the planet for generations to come and in action that prevents long term irreparable damage to the planet. One of these options is solar power, the benefits of harnessing the suns energy to create a renewable energy supply that can power heating and electric, is relatively low risk, high benefit and an investment in the future of the planet. Solar energy also offers a path to zero carbon net emissions in the supply chain, over the long term, which is better for the environment and creates less dependency on the more damaging and finite resources the are fossil fuels. In order to support the transition to solar as a viable source of energy supply, electricians are up-skilling and getting training, which is enabling them to become proficient in creating, installing, supporting, servicing and repairing solar grids, that are localized to the home, or are part of larger industrial or ccommercial farm unit.
What is driving the change to solar
Historically solar energy has been considered expensive and inefficient. However, that view has changed in more recent times, with the lowering of prices through competitive technological developments, marketing and sales strategies as well as solar panel grants. There are also grants available to business as an incentive to develop solutions in the solar energy space, as well as for homeowners looking to switch to solar; the grants are backed by a government initiative and are subject to the larger EU Renewable Energy Directive, which requires all member countries to set a strategy to reach a 20% renewables target by 2020. Most countries are not on target to hit this
This directive would not apply to the UK in the wake of the UK’s departure from the EU, but the continuation of this directive will be subject to the UK government’s view on directive alignment, policy cost and feasibility.
Let's briefly talk about grants
There are several structures to the grants, there is the Feed in Tariff scheme, this focuses on those estates that generate electricity by solar power or wind turbines. The estates receive an amount of money for any surplus of each unit kilowatt per hour that they return to the grid. Thou the scheme ended in 2019 in the UK, it is still available to those that registered prior to 2019. The scheme lasts 20 years from the date of registration and is dependent on the type of technology, size of the system and when it was installed. This offers a significant period by which homeowners could make savings on energy bills, and improve the environment, all of which justify the investment in solar technology.
Installation by panel sizes
Homeowners are required to use a certified electrician installer from a reputable energy provider or registered electrician supplier. The two-sub class of payments are the generation tariff, this is the amount of energy produced and consumed, and costs vary between £6.38 and £13.88 per Kwh (kilowatt hour). The export tariff relates to the surplus the homeowner sells, for which the rate is £4.77 per unit in Kwh. Since the scheme closed, the Feed in Tariff has been replaced by the SEG (Smart Export Guarantee). The scheme although different at its core, focuses on small-scale low carbon electricity generators to receive payment for any surplus energy sold back to the grid. One major difference is this is not supported by any government grant; instead it is incumbent upon energy suppliers with an excess of 150,000 customers to offer the SEG service, those that have fewer customers, can opt in on a voluntary basis.
Homeowners with 5MW (Megawatts) of capacity are eligible for SEG and they are also required to install a smart meter to more accurately measure their KW exports. Homeowners should consider the installation of solar thermal panels to heat their homes; this is part of the (RHI) Renewable Heat Initiative, which was an industrial initiative that was expanded to include domestic properties in 2014. It’s purpose is to enable change in households from traditional renewable heat technologies, to those such as solar thermal panels and biomass boilers, these offer lower carbon emissions and form part of the strategy to reduce the overall country’s carbon emission in line with the EU target.
Support for the solar programme
It is well documented that current methods of supplying energy are contributing to global climate change, the initiatives to reduce carbon emission require change vehicles, technology enablers and incentives to make homeowners switch. The RHI is a 7-year support programme with quarterly payments depending on the technology being used and the latest related tariffs. One pre-requisite is the property must have a valid EPC (Energy Performance Certificate) that must provide an assessment and demonstration of how it could be improved.
Alternative schemes and how they benefit the homeowner
Another popular scheme is the Free Solar Panel scheme, this enables those property owners who cannot afford solar panels to rent out their roof footprint to solar panel companies, who would take responsibility for installation, maintenance, and repair all for free, in compensation they would receive the (FIT) Feed in Tariff. As well as this scheme there is the Solar Buyback Scheme. This is a scheme where a lump sum amount from the companies that provide the energy is rebated to the homeowner for the surplus, instead, this is returned to the company leasing the solar panels. The company gets to collect the FIT rebate, which the homeowner would. This should be weighed by assessing how the lump sum compares to the FIT, and if this scheme works for the property owner.

How can homeowners evaluate the benefits
It is also for the homeowner to determine the advantages and disadvantages of renewable energy, as a guide, advantages include, low maintenance costs, varied applications, progressive technology, reduced electric bills and a renewable energy source. The disadvantages include weather, cloudy, overcast could all affect both the amount and the level of energy generation, the cost for a significant roof footprint of solar panels and in-direct pollution.
Maintenance of solar panels - cleaning
In reference to Low maintenance costs this centre's mainly around keeping the panels clean, this should be done a couple of times a year or if they are fouled for some reason. Specialised tradespeople run cleaning companies for solar panels they can charge between £25 and £35 pounds for the service and offer 20 to 25 year warranties.
Maintenance of solar panels - core units and cables
The inverter also know as a solar inverter or PV inverter is an electrical converter, it takes the variable (DC) direct current output from a (PV) photovoltaic solar panel converting it into alternating AC (alternating current) this process utility can supply a commercial electric grid, or be used by local off-grid networks. The inverter needs to be replaced every 4 or 5 years due to the working nature of the device, which results in wear and tear over time. Cables should also be replaced to ensure sustained efficiency
Benefit, after the initial outlay, the running cost over the life of the panel, is less costly for both maintenance and repair.
Solar has other applications also
Solar energy can also be used in solar thermal panels to heat water; it absorbs the heat (via collectors) of the sun via a photo voltage process, takes the heat-transfer fluid (water) to the hot water cylinder, this provides your property with free heated water. PV (photovoltaic) can be used to generate electricity; this not only has domestic applications but has applications where access to power is limited or not possible from the grid, such applications include to distil water in regions with limited clean water supplies.
The big save with solar
With everyone looking to reduce their electric bills and big suppliers monopolizing market rates, through cartel based activities and strategies. Using a solar system will see your electric bills reduced, how much, this will largely depend on the size of your unit, and how you and your household use your electricity. Saving on your energy bill is something everyone would like to do, the benefits of electricity generated by solar power is it is possible to sell the surplus energy back to the grid creating another source of income in the form of a reabate on surplus returned not consumed at source.
Technology developments
Technology developments in the solar power industry are advancing at quite a pace; one example is Sharp’s introduction of transparent solar energy windows. There are also breakthroughs in quantum physics and nanotechnology that when applied to solar technology and devices, increases their effectiveness and capability in power generation.
Solar initial costs
Solar panels can be expensive when initially purchased, the average price of a solar panel system occupying a footprint of 8 meters squared with a system size of 1kW can cost between £1500 and £3000, the upside is there is a £640 pound cumulative potential return (depending on usage and surplus returned) with divisible increments being paid year by year for 20 years.
Challenges with solar installations
Solar panel technology is constantly evolving and improving, and with greater market adoption, and access this is bringing the initial cost down for homeowners. Solar panels require a large footprint of occupancy on a roof, therefore, it may not always be possible to reach your aspirations of an extended footprint beyond what is safe and workable for your property, in instances like this a garden approach can be considered as long as there is sufficient access to sunlight.
Indirect pollution and solar
When we talk about pollution, we know that it is the indirect emission that come in the form of carbon emissions from logistics and transportation of panels, as well as the manufacturing process associated with photovoltaic cell production.
Solar dependency
Solar is dependent on the sun, so if there are a few days of consecutive rain and the weather is overcast, there is a noticeable drop in power generation.
