What does it all mean?
Capacity: St John’s School’s ecoLibrary solar roof is made up of 45 separate solar panels with each producing 0.285kWp (kilowatt-peak), a total of 12.8kWp. A typical house has between 1.5kWp (6 panels) and 4kWp (16 panels) installed.
Power: This shows the amount of energy currently being generated by the solar panels, on bright sunny days this will be higher than on cloudy winter days.
E Day: This shows the amount of energy generated for the current day, 1kWh (kilowatt-hour) is equivalent to running a 28-inch TV for 8 hours or a light bulb for 50 hours.
E Total: This shows the total amount of energy generated by the solar panels since they were installed at the end of June 2015.
Total Yield: This shows the total value of the energy generated by the solar panels since they were installed at the end of June 2015.
Total Plant: This shows the number of tress that would otherwise have had to have been cut down and burnt in order to produce the same energy generated by the solar panels.
Total Avoid: By generating electricity using solar panels St John’s will save around 6.5 tonnes of carbon emissions per year, 1 tonne of CO2 is equivalent to driving a car for 3000 miles, driving a bus for 5791 miles or a 10321 mile train journey.
