How Much Could I Save?

Plug In Solar DIY kits are a great way to save money by generating your own FREE electricity.  The simple equation is: The BIGGER the Plug In Solar Kit, the BIGGER the saving.

The total savings over a 20 year period on a OCTA (2kW) Plug-in Solar system are estimated to be over £13,950.00. This equates to an average saving of over £697.00 per year over the 20 year period. More information on these calculations can be found here.

Use our handy calculator to estimate your own personal energy usage and requirements.  Simply choose your appliance, enter the amount of hours you use it for per week and then click on the ‘Calculate Totals’ button.  For reference, a Plug In Solar OCTA 2kW Kit will produce around 35kWh per week that can be used to power these appliances.

Energy Usage very high? This helpful guide illustrates the most energy hungry appliances in the home, and ways in which you can reduce your energy usage: What Uses Watt

A OCTA (2kW) Plug-In Solar Kit solar panel will produce 2kW per hour at its peak. On average a OCTA (2kW) Plug-in Solar kit, which consists of eight 250W panels, will produce enough energy (1,972kWh), in one year, to power:

These figures assume that you have south facing solar panels, pitched at a 35 degree angle, you pay 14.05p per unit of electricity (Standard rate as of February 2015 source: Energy Saving Trust) and 100% of the solar electricity that you generate will be used in your home. Calculations assume an annual energy price inflation of 10% & include solar radiation & system losses, in a western UK location, due to Temperature 6.8% and Angular Reflectance 2.9%, as well as other losses (e.g. Cables, Inverter) of 12%. The performance of solar PV systems is impossible to predict with certainty due to the variability in the amount of solar radiation (sunlight) from location to location & from year to year. This estimate is based upon the Government’s standard assessment procedure for energy rating of buildings (SAP) and is given as guidance only. Illustrative solar PV performance figures only. Figures are given in good faith but do not constitute “Financial Advice”. Yearly PV output uses a factored degradation over time based on industry estimates. Photovoltaic Panels will not be shaded (e.g. by Trees or Buildings) as shading affects PV output. Please note: Specific appliance ratings and equipment age will affect energy consumption and these examples are guidelines only.
