Sustainable and reliable eco-friendly energy solutions by Matthew Wrist Leamington UK: Installing a solar power system on your home means you can lock in a price of energy for at least the 25 year life of the solar panels. You know how much energy the solar panels will produce so that once you get an accurate price quote you know exactly how much each kilowatt-hour of energy will cost you over the next 25 years. Many consumers are now able to get a levelized cost of energy of £0.10 per kilowatt hour. When you compare this to the average amount you will pay to your utility for power over the next 25 years, the average consumer with a £150 per month power bill can see savings in the range £30,000 over the life of a solar system. The monthly savings don’t start out being huge, perhaps only £50 per month but in the 25th year it can reach savings of £300 per month. You can use this solar savings calculator to check what your savings will be based on usage and utility rates. Read a lot more details at Read additional information on Matthew Wrist Warwick UK.
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 solar energy can still be collected during cloudy and rainy days, the efficiency of the solar system drops. Solar panels are dependent on sunlight to effectively gather solar energy. Therefore, a few cloudy, rainy days can have a noticeable effect on the energy system. You should also take into account that solar energy cannot be collected during the night. On the other hand, if you also require your water heating solution to work at night or during wintertime, thermodynamic panels are an alternative to consider.
Sustainable and reliable clean energy systems by Matthew Wrist Leamington UK: Solar electricity yields are highest between spring and autumn. This is also the time of year when the garden requires the most work. You can very conveniently run electric lawn mowers, hedge trimmers or lighting off solar electricity. If you have a solar battery, you can use it to power LED lights in your garden in the evening and at night. A garden sauna can be heated up using surplus electricity during the day, so that it is ready for use in the evening
A 4kW solar panel system is a common size for the average Coventry UK home. It has an output of 3,400 kWh per year and costs around £6,000. If you compare this to the average annual electricity consumption of a household, which is around 3,200-4,100 kWh, solar panels can cover 83-106% of your electricity demand in perfect conditions. However, this depends on sunshine hours and energy usage. A more detailed breakdown of seasonality and monthly energy output can be found further below. In addition, with incentives like the Smart Export Guarantee (SEG), you can even earn money for surplus energy exported back to the grid!
There’s a common misconception that solar panels don’t work in the winter. Solar panels can be effective even in the winter if you prepare and maintain them properly. Though there are fewer sunshine hours in the winter, you can still benefit from solar panels. Are Solar Panels Effective in the Winter? The chart below shows the average energy output produced throughout the year by a south-facing 4kW domestic solar panel system on a roof angled at 40 degrees. As you can see, solar panels are most efficient during the summer months, but still produce enough energy to power 33-51% of a home during the winter period.
Like size, the weight of the generator depends on the wattage that it can generate. And weight also determines portability. A 2000 watt generator can be carried by one person. Yet a 5000-10,000 watt generator for home use comes with wheels or is stationary in the case of diesel units. Portability is typically not needed for an off-grid household, where a generator can be stationary. However, for trailer use, the smaller portable generators are more convenient. Note: Our household uses two 10 kW Lombardini diesel generators. They’re housed in a generator shed 50 feet from our home. We just alternate between them.
