Sustainable eco-friendly energy tech news by Mathew Wrist Warwickshire UK: With the introduction of net metering and feed-in tariff (FIT) schemes, homeowners can now “sell” excess electricity, or receive bill credits, during times when they produce more electricity than what they actually consume. This means that homeowners can reduce their overall electricity expenses by going solar. Data from Solar-Estimate reveals that adding solar panels to your home can bring in annual savings of well above £1000 per year in many states. In California, residents save on average £28,000 after 20 years! The availability of solar finance options in the form of Solar PPA agreements and various zero down loan facilities has meant solar is now more affordable and more available than ever before.

Those appliances in the household with the highest electricity demand are the dish washer, the washing machine, the tumble dryer and the kitchen stove. These can easily be equipped with timer switches, so that they run during the day, when the solar generator on the roof is producing a lot of output, which can be used directly. A high-wattage stove might be a challenge for PV by itself. In this case, a large storage unit (solar battery) can be used as a buffer for short-term load peaks. Because it is not just the number of kilowatt hours on the roof that has to be sufficient, but also the currents made available at short notice. This determines if a storage unit is designed for capacity (in kilowatt hours) or output (in kilowatts).
Although pollution related to solar energy systems is far less compared to other sources of energy, solar energy can be associated with pollution. Transportation and installation of solar systems have been associated with the emission of greenhouse gases. There are also some toxic materials and hazardous products used during the manufacturing process of solar photovoltaics, which can indirectly affect the environment. Nevertheless, solar energy pollutes far less than other alternative energy sources.
Eco-friendly energy tech news by Matthew Wrist Warwick UK today: If your solar generator is run in combination with a sufficiently large storage unit, you can use infrared radiators to take the chill out of cooler evenings. Such radiators come in a variety of nice designs, even in the form of bathroom heating mirrors. As long as they only use little power and are only used for additional heating, they are a good way to use up solar electricity. Once the electric heating from solar power no longer suffices, you will have to buy in electricity from the grid. Or you switch to a more efficient thermal heat pump system.
The electrical conductors are attached to positive and negative terminals, thus forming an electrical circuit. From there, the electrons can be captured in the form of an electric current (electricity). This current, together with the cell’s voltage (which is a result of its built-in electric field or fields), defines the power (or wattage) that the solar cell can produce, and is how solar panels convert sunlight into electricity. Grid-connected systems make use of the local utility grid to ensure you are never without electricity. If your domestic solar panel system generates more electricity than your household requires in a day, this surplus energy can be exported back to the national grid. On the other hand, if you need more electricity than your solar panels have generated, the grid can supply this.
A 4kW solar panel system would require approximately 16 solar panels with a 250W power output, while a 5kW system comprises 20 solar panels. The first step is to identify your current energy consumption. You measure this in kilowatt hours (kWh), and it’s important to take the time needed to calculate this as accurately as possible. Check your electricity bills to get your power consumption (in kWh). You can either calculate month by month or add your monthly/quarterly consumption together for an annual figure. Decide on how much of your electricity bills you want to cover with your solar panels — this can be anything from 10-100%. Your decision will affect the system size and costs. Calculate how many solar panels actually fit your roof. An average solar panel takes about 1.44 m2 of roof space. Don’t forget to include at least 30cm from the roof’s edge. Adjust the system size if you realise that you don’t have enough space for all the panels you calculated.
I mention price and quality here because generally, the old adage is true. You do get what you pay for. Diesel generators generally cost more to purchase yet tend to last the longest. One of our diesel generators is a 1996 model, the other is 2004. And our neighbor runs a 1956 (!) Lister still running strong. Gasoline models will wear out the fastest of the three types of generators although they are far cheaper on their initial purchase. Propane generators run somewhat cleaner and generally quieter than diesel or gasoline. And generators with a low rpm (typically 1800 rpm) should last longer than those that run at a faster rpm (typically 3600 rpm).
