Photovoltaic (PV) solar panels turn the sun’s energy into electricity to either partly or completely replace your home’s traditional supply. To work to their full effect, solar panels must be installed in a manner that insures they can generate as much energy as possible. They should only be installed on south-facing roofs or locations where they spend as much time in full sunlight as possible.
This means that with most renewable energy installations there are times when PV panels can generate more energy than is being used in the home This can be for a number of reasons:
Traditionally, most people with solar panels sell this surplus energy back to the National Grid. However, this actually reduces the possible savings as it is likely that you will then have to buy energy back from the Grid during peak times in the evenings when your solar panels aren’t able to generate electricity for you.
Are there benefits to selling energy back to the National Grid?
Most domestic renewable energy installations are connected to the National Grid, where any excess energy can be sold back to the supplier. There are two ways this can be done, net metering or simple energy exporting.
Net metering is the most common. It means you earn the same price per unit when exporting energy from your home as it costs you to purchase the energy in. Despite this, the system involves large amounts of paperwork and manual tracking. It also requires the purchase and installation of an OFGEM approved export meter. As well as this, if your system is built only to fulfill your energy requirements, rather than exceed them, this option can be costly.
Simple energy exporting is more simple, yet less common. With this system, excess energy is simply fed back into the Grid as it is generated, however you receive less per unit than it costs to purchase electricity - meaning this option can make your overall energy savings marginal or even negative.
Neither option offers a clear benefit to selling energy back to the National Grid. However, selling back to the grid is not the only option available, it is possible to use any surplus energy within your own home in other ways.
Turning surplus energy into self-consumption with the immerSUN
The immerSUN is a state-of-art energy saving green gadget. It works as an automatic power controller, diverting surplus self-generated electricity from solar and wind renewables systems to element-driven devices within the home rather than it being exported back to the Grid.
It makes your entire home as energy efficient as possible by ensuring you self-consume the maximum amount of energy generated from your renewable system. In some cases this can amount to 100 per cent of self-generated energy used in the home compared to just 30 per cent on average with just solar panels alone (read more about how it works).
‘Self-consuming’ renewable energy is extremely cost effective; an immerSUN device can save a household more than £250 a year off its energy bills, that’s an average saving of 15 pence for every kilowatt hour generated. Up to three immerSUNs can be used at once in tandem for larger renewable systems - they are compatible with all domestic renewable energy generation technologies and can divert surplus power to hot water and heating systems, kitchen appliances and even hot tubs or swimming pools.
Costing just £348 (inc.VAT), it can pay for itself in less than two years and save its owner as much as £5,000 over its lifetime, which should easily exceed 20 years (buy direct from us).
Installing an immerSUN in your home couldn’t be easier; the device is compatible with all microgeneration systems and features a fully programmable boost function, which can control up to three heaters simultaneously.
Its performance can be monitored remotely from anywhere thanks to its myimmerSUN smartphone, tablet and PC app software.
The ImmerSUN is the only device on the market meeting each and every global compliance certification. It also conforms to all EU legal requirements relating to the safety of household appliances, unlike 80 per cent of all other microgeneration power diverters on the market.
The device is unique in that its patented truSINE™ Pulse-Width Modulation (PWM) control technology completely removes any risk of overload by keeping the delivered power as a true sine wave, regardless of any power spikes.
The immerSUN is already available to solar panel owners in the UK, France, New Zealand and The Pacific Islands, and the firm hope to extend exports worldwide in the near future.
