Higher efficiency panels (20% or greater) generate more power in a given space. Monocrystalline panels are generally more efficient than polycrystalline panels. Bifacial panels are another option, generating power from both sides, increasing output, especially in environments with reflective surfaces (like snow). Consider the total wattage of the included panels and whether they’re sufficient for your typical energy usage and sunlight availability.
Inverter Features & Monitoring
The inverter converts DC power from the batteries and panels into AC power for your appliances. Features to look for include: MPPT (Maximum Power Point Tracking) charge controllers, which maximize energy harvest from the solar panels. WiFi connectivity allows remote monitoring of system performance via a smartphone app. UPS (Uninterruptible Power Supply) functionality provides seamless backup power during grid outages. Input power adjustment can extend battery life. A pure sine wave inverter is a must – it delivers clean, stable power that’s safe for sensitive electronics.
