Get your DIY solar project over the finish line with professional installation support, safety compliance, and official UK grid certification. RenewSolar provides expert technical assistance as a standalone service—you provide the hardware, we provide the expertise.
Our Specialist DIY Services
- Compliance & Safety: Verification that your system meets UK electrical standards (BS 7671) and building regulations.
- Hardware Installation: Professional mounting of panels, inverters, and DC cabling to ensure structural integrity and electrical efficiency.
- Battery Storage: Integration of lithium-ion or lead-acid battery stacks, including BMS (Battery Management System) configuration.
- System Optimization: Production analysis to ensure your string configuration and orientation maximize kWh output.
Testing, Commissioning & Paperwork
The final step of any installation is ensuring it is legal and recognized by the DNO (Distribution Network Operator). We handle the technical testing and the complex filing process:
| Service | Description | Requirement |
| G98 Application | For systems up to 16A per phase (approx. 3.68kW). | Standard small domestic systems. |
| G99 Application | For systems exceeding 16A per phase. | Larger domestic or commercial arrays. |
| MCS Certification* | Comprehensive system testing and certification. | Necessary for Smart Export Guarantee (SEG) payments. |
| Commissioning | Live testing of voltage, earthing, and safety cut-offs. | Required for insurance and warranty validity. |
Why Use RenewSolar for DIY?
- Hardware Independence: You are not required to purchase components from us. We install and commission any hardware you have sourced.(provided its safe and legal)
- Expert Oversight: Avoid common DIY pitfalls such as incorrect wire sizing or poor weatherproofing.
- Grid Approval: We bridge the gap between your physical installation and the legal requirement for DNO notification.
- Experts: We handle the technical and documentation.
- On or Off Grid: You may want a off grid or grid system installed.
Notes: Proper commissioning is the difference between an “off-grid hobby” and a legal, revenue-generating home power plant connected to the grid.
*We use third party certification for MCS systems as we dont really believe in this. The certificate offer may be limited due to the rules and regulations of a MCS installation.
Off-Grid Solar & Storage Solutions
RenewSolar provides specialised engineering for systems operating independently of the national grid. Whether for remote cabins, mobile units, or complete energy independence, we offer technical support and installation for standalone power systems.
Off-Grid Service Categories
- System Design & Sizing: Calculation of daily Wh (Watt-hour) consumption to ensure your battery bank and solar array meet your specific load requirements throughout the year.
- Hardware Integration: Installation of off-grid inverters, charge controllers (MPPT), and DC-coupled systems.
- Battery Bank Specialist Support: Professional setup of high-capacity storage, including configuration of charging profiles for Lithium (LiFePO4) or Lead-Acid/AGM cycles.
- Backup Generator Integration: Seamless wiring of Auto-Start generators to provide redundancy during low-solar periods.
Comprehensive DIY & Off-Grid Checklist
Customers utilising our standalone installation service benefit from:
- Hardware Flexibility: We support all major off-grid brands (e.g., Victron, Pylontech, Growatt and Sunsynk).
- Compliance: Even off-grid, we ensure your DC and AC wiring meets safety standards to prevent fire risks and equipment failure.
- Performance Testing: Full diagnostic check of your array’s production versus the storage system’s efficiency.
- Experts: Providing information and the missing requirements for a safe and managed system installation.
