Solar Roof Design Company was set up to give Investors, Developers, EPCs, Installers, and Commercial Companies the support route to getting independent good value professional advice at low cost, helping you achieve your best investment in Solar installations.
Using PV-SOL professional design software to generate a full installation report for all sizes of systems on Roofs and Ground Mounts.
We also offer onsite roof or ground mount surveys including to scale measurements and drone footage .
Included in all reports is a full financial return on investment profile including reinvestment triggers, Utilities costs from grid and Export to grid repayments.
Solar Roof Design Company are design consultants ONLY who have been installers previously.
Our objective is to give Technical Design Advice and sound return of investment information within the design report showing pay back periods vs cost to install.
All measurements are either taken from the Installers survey or measured direct from Google Earth giving the most accurate installation information to the install technicians
Shading from Chimneys, trees and adjacent properties can pull a system's performance down considerably and most companies that don't have this software cannot accurately advise of true system performance. Shading and performance on dual and treble aspect roofs all give varying outputs over the 24hrs and 365 days per annum.
All string wiring diagrams are specific to the design and correlate to the inverter and the actual panels. This eliminates any confusion on the day of installation and can determine materials used prior to installation
Our reports are specific to your actual property's nearest weather station. Based on 20 years historical Meta Data collected and collated by the Met Office. Giving more accurate outputs than any free online services.
Correct orientation is taken from Google Earth or other sources to enable a more accurate output for the design.
Correct inverter choice will be required to match up with array size, panel type and how many different directional roof aspects, ie the number of maximum power point trackers (MPPT) inputs. Especially when an array is larger than the maximum capability of the inverter inputs. Most inverters will require to be replaced approximately within 7 -10 years and there is evidence that they will fail quicker when an array is oversized vs inverter capability.
Correct panel choice needs to match up to the designed system size and Inverter, These are all factors that contribute to the best overall system performance. For your information please see below hyperlink to the top 10 panels in the market place. Panel performance guarantees are commonly for 25 years and most panels degradation is approximately 15% over that period, which is factored into the Report.
Batteries are an economic way to improve your systems output consumption. However, most people think by adding batteries they will get to use ALL of the energy produced from the system and use it. This is not the case and normally you will be exporting to the grid when the battery is full. Unless you install quite a large battery bank, which will then become uneconomical as an investment Vs Return. Most people are not advised that batteries will need replaced in approximately 10,000 cycles or 7-10 years.
Battery installations commonly will not be wired to power a property in the event of a power failure unless it has been specified with your installer that an uninterruptible power supply (UPS) has been agreed to be installed.
Sizing a house can be difficult as most people mistake Kilowatt Peak (KWp) Vs Kilowatt Hours (KWhrs). Solar Roof Design reports produce data analytics in Excel format over 25 years for all parameters helping people understand system performance and can give out production data down to the 1 hour increments based on 20 years of meta data. However the client can work out the annual KWhs consumption from their whole years utilities bills. However the Client will find it very difficult to work out what their
KWP load is.
KWP example: 4no 250watt panels on your roof = 1KWP installed in high sun they can produce 1KWh every hour, in low sun it can be less.
KWhr example: if you have a 1kwp blow heater in your house and you run that for 1hr you will use 1 Kwhr.
