Solar installation by CRSCommercial solar in Norwich, Cambridge & Great Yarmouth
CRS Electrical installs commercial solar PV systems across Norfolk, Suffolk and Cambridgeshire. Based in Great Yarmouth, we support businesses in Norwich, Cambridge, King’s Lynn and surrounding areas. We help you understand the options, installation requirements and potential benefits before committing.
Could commercial solar work for your business?
Solar generates during daylight hours, making it worth considering for businesses with daytime electricity demand. Electricity used directly can reduce purchases from the grid. We assess consumption, usable roof space and the proposed system together. A large roof does not automatically mean filling it with panels is the most suitable investment.
A system designed around your energy use
We discuss electricity consumption and tariff, operating hours, seasonal changes, significant equipment demand, roof orientation and shading, existing distribution and planned machinery or EV charging. Recent bills provide a starting point. Half-hourly consumption data, where available, helps us assess the overlap between demand and generation.
Commercial rooftop solar
We assess warehouses, workshops, offices, retail premises and other suitable buildings. Rooflights, access routes, shading and existing equipment affect the layout. Panel and inverter selection considers the electrical requirements and installation environment.
Is your roof suitable?
We review roof type, condition, available information and mounting arrangements. Where structural assessment or specialist roofing input is needed, we explain it and agree responsibilities. Planned roof repairs and, for leased premises, the owner’s agreement and lease arrangements need consideration.
Understanding generation, savings and payback
We explain estimated generation, expected onsite use and assumptions behind potential savings. Where payback is estimated, we identify the costs included. Orientation, shading, weather, consumption patterns, tariffs, export arrangements, equipment losses, maintenance and future equipment costs affect the assessment. Generation and savings are estimates rather than guaranteed outcomes. We distinguish generation, onsite use and export.
What affects the cost?
Costs depend on system size, panels, inverters, roof access, mounting, cabling, containment, electrical alterations and necessary specialist assessments. Connection requirements and existing installation work can affect price. The quotation sets out inclusions and exclusions.
Electrical infrastructure and grid connection
We assess connection points, cable routes, distribution and inverter positions. Required electrical upgrades are identified. We explain applicable distribution network operator requirements and who manages the application or notification. Prior approval, where required, must be addressed before connection. Network conditions can affect export, design, costs and programme.
Solar, batteries and future EV charging
Battery storage may be worth assessing where use and generation do not align. Suitability depends on surplus generation, when power is needed and equipment costs. Tell us about future batteries or EV charging so we can consider space, cable routes and capacity. Backup power requires a specifically designed arrangement; a battery does not automatically provide it.
Installation around your operations
We agree scope, contacts, access and programme. Deliveries, roof access, working areas and restrictions are discussed. Shutdowns are coordinated with your team. Phased or out-of-hours work can be arranged subject to suitability and availability. Equipment availability, approvals and preparatory work can affect timing.
Testing, monitoring and handover
We inspect, test and commission within the agreed scope. We explain operation, isolation and monitoring. Available monitoring depends on equipment and connectivity. Handover includes relevant certification, equipment information and warranties, with fault-reporting and maintenance requirements explained.
Your included 30-day follow-up
Every CRS solar installation includes a follow-up check around 30 days after completion, by phone with a remote monitoring review or an onsite visit—whichever you prefer. We review the available system information, check that it is operating as expected and answer your questions. We help you make better use of the electricity your panels generate. Where battery storage is installed, we review its settings against your energy use and tariff. If anything needs further investigation, we explain the next steps and arrange appropriate follow-up.
Frequently asked questions
How many solar panels does our business need?
We assess electricity use, usable roof space and connection requirements together. Half-hourly consumption data, where available, helps us understand the overlap between demand and generation.
Can our business stay open during installation?
Often work can be coordinated around an occupied building. Access restrictions and necessary shutdowns are agreed with your team; we explain what the proposed installation will involve.
Will solar cover all our electricity use?
Usually grid electricity is still needed. Output varies through the day and year, while your business may use electricity outside generating hours.
Can solar be installed on leased premises?
The owner’s consent and lease arrangements need addressing. We discuss the building and available information before planning the installation.
Will we need planning permission?
Requirements depend on the building, location and proposed installation. Relevant permissions need to be established for the specific project.
What happens to surplus electricity?
It may be exported, stored or curtailed depending on the system and connection. Export payments depend on eligibility and supplier arrangements.
Will the system work during a power cut?
A standard grid-connected solar system generally shuts down during a power cut. Backup requires suitable equipment and a specifically designed arrangement.
Can we add batteries or EV charging later?
Potential additions depend on compatibility, space and electrical and network capacity. Tell us your plans early so we can discuss practical allowances.
How are savings and payback calculated?
We explain generation estimates, expected onsite use, tariffs, costs and other assumptions. Weather, energy use, equipment performance and prices affect the outcome; estimates are not guaranteed savings.
What support is included after installation?
Every CRS solar installation includes a follow-up around 30 days after completion, by phone with remote monitoring or an onsite visit, according to your preference. We review available system information and explain any further action needed.
