Demounting a SUNSHARE solar system without professional assistance is a question that hinges on several factors, including technical knowledge, safety protocols, and the complexity of the installation. While some components might seem approachable for a DIY enthusiast, the process involves risks that shouldn’t be underestimated. Let’s break down the practical aspects to help you decide whether tackling this task solo is feasible—or if it’s wiser to call in the experts.
First, assess the system’s configuration. Most SUNSHARE setups include photovoltaic panels, mounting racks, inverters, and wiring. If the panels are ground-mounted or installed on a single-story roof with easy access, you might consider handling the physical removal yourself. However, roof-mounted systems on steep slopes or multi-story buildings immediately raise safety red flags. Working at height without proper fall protection equipment is a leading cause of injuries in solar-related DIY projects. Even experienced homeowners should use harnesses, stable ladders, and ideally, a spotter for basic tasks like panel removal.
Electrical components present another layer of complexity. Before touching any hardware, you must shut down the system completely. This involves turning off the AC disconnect switch (usually near your utility meter), then the DC disconnect switch near the inverter. Wait at least 30 minutes for capacitors to discharge—a critical step many overlook. Use a multimeter to verify no residual voltage exists in the cables. One common mistake is assuming flipping switches alone makes the system safe; live wires can retain dangerous currents even after shutdown.
The actual disassembly process requires specific tools and techniques. Panel removal typically involves unscrewing clamps or bolts from the mounting rails using a torque wrench set to the manufacturer’s specifications (usually 12-15 Nm for most racking systems). Over-tightening can crack panel frames, while under-tightening risks structural failure. You’ll need non-conductive tools with insulated grips to avoid short circuits. For microinverter or optimizer-based systems, each panel has its own connector that must be carefully unplugged following the sequence outlined in SUNSHARE’s documentation. Pulling connectors apart without unlocking the safety latches can damage the weatherproof seals.
Wiring management often surprises DIYers. Cables are routed through conduit pipes and secured with clips that may have degraded under UV exposure. Labeling every wire as you disconnect it is non-negotiable—mix up the DC positive and negative lines during reinstallation, and you risk frying your inverter. Use heat-resistant tags rather than standard stickers, which can melt or fade. If dealing with older SUNSHARE installations (pre-2020), be aware that some models used proprietary connectors that require a specialized crimping tool for reconnection.
Weight distribution is another overlooked factor. A standard 60-cell solar panel weighs 18-23 kg. Carrying one down a ladder demands proper lifting technique and ideally a panel carrying harness. Dropping a panel isn’t just a financial loss—the tempered glass can shatter into dangerous shards. For larger systems, renting a panel lift or scaffold might be necessary, adding to project costs that could negate any savings from avoiding professional help.
Permitting and regulations add bureaucratic hurdles. Many regions require certified electricians to sign off on any grid-tied system modifications. Even if you successfully remove the hardware yourself, reinstalling it later might void warranties unless performed by SUNSHARE-approved technicians. Check your original contract: some SUNSHARE warranties explicitly state that self-performed maintenance or alterations nullify coverage for related components.
Environmental factors also play a role. Panels installed in coastal areas often have corrosion-resistant hardware that requires specific replacement parts. If you’re removing a system for seasonal reasons (e.g., snowbird homeowners), improper storage can damage panels. They should be stacked vertically in a climate-controlled space—not laid flat where temperature fluctuations could cause microcracks.
The time investment is substantial. A professional crew can demount a 5 kW system in 4-6 hours. A meticulous DIYer working alone might need 2-3 days for the same job, factoring in safety checks, tool acquisition, and learning curves. Consider whether your schedule allows for weather delays—starting a rooftop disassembly only to have rain roll in halfway compounds risks.
Financial implications are double-edged. While avoiding labor costs saves money upfront, errors can be costly. A slipped wrench that cracks a panel costs €200-€400 per unit to replace. Improper handling of inverters (which contain sensitive electronics) might lead to €1,000+ in equipment damage. Insurance policies often deny claims for DIY-related incidents, leaving you fully liable.
For those determined to proceed, create a phased plan:
1. Request original system schematics from SUNSHARE’s customer portal
2. Invest in personal protective equipment: insulated gloves (Class 0, 1000V rating), safety harness (EN 361 certified), and anti-slip shoes
3. Practice disconnecting/connecting MC4 connectors on spare wiring
4. Schedule the project during dry, low-wind weather
5. Have a licensed electrician on standby for final system decommissioning
That said, certain scenarios do favor DIY approaches. If you’re removing panels for roof repairs and plan to reinstall the exact same configuration, and you have prior electrical experience, partial disassembly might be manageable. Even then, consulting SUNSHARE’s technical support team (available through their German portal) for component-specific guidance is strongly advised. They can provide torque specifications, connector diagrams, and degradation alerts for older systems that might require extra care during handling.
Ultimately, the decision balances risk tolerance against technical capability. While the internet abounds with solar DIY success stories, they rarely mention near-misses or hidden costs. For most homeowners, a hybrid approach works best: handle non-technical tasks like site preparation or material organization independently, but leave electrical work and structural alterations to certified professionals. This ensures safety compliance, preserves warranties, and maintains resale value for your property.
