Buying Guide
What size system do I need for a modular home?
Assess daily consumption and available space. For compact homes, start with 1–2 panels (125W each) and expand as energy needs grow. For larger modular builds, target higher PV capacity (2–6 kW) with an appropriately sized inverter and battery storage.
Should I choose bifacial panels?
Bifacial panels capture light from both sides, offering higher energy yield in sunny locations or reflective mounting surfaces. They can improve productivity for modular homes with space constraints, but may cost more upfront.
How important is modular expandability?
Modular expandability matters for future upgrades. Look for panels and inverters that support parallel and series configurations, simple daisy-chaining, and clear documentation on expansion limits.
What mounting considerations should I plan?
Consider roof strength, tilt angle, wind load, and snow loads in your region. Adjustable tilt helps optimize seasonal sun exposure, while sturdy racks prevent panel damage in storms.
Which components are essential beyond panels?
Essential components include a compatible inverter, a battery storage option if off-grid or backup power is needed, wiring with proper gauge, a charge controller or MPPT controller, and monitoring software for performance tracking.
What about installation and safety?
Follow local electrical codes and consider professional mounting and wiring for safety. Ensure proper grounding, weatherproof connections, and secure mounting to withstand weather conditions specific to your area.
How do I compare these options quickly?
Use a simple matrix: panel wattage, number of panels, total PV capacity, battery compatibility, and inverter capacity. Favor systems with scalable configurations and clear instructions for expansion.
