Solar dealers

Start by identifying your energy goal, available space, and whether you need panels, a complete solar kit, or a compact appliance solution. Solar dealers typically group offerings into three categories: solar panels, solar kits, and small-appliance options, with brands like Sunshine, DP, Qasa, and Generic. Then check system voltage compatibility (commonly 12V for small setups) and ensure the choice works with your inverter and battery setup.

Wattage and voltage compatibility are the most complex attributes to compare. Wattage determines daily energy production, while voltage dictates matching with your charge controller and inverter. In Sunshine listings you’ll find 100W and 150W mono panels, and you can combine two 100W panels to reach 200W. Monocrystalline panels are typically more efficient and space-saving than other types, so choose based on your daily needs and available mounting area.

Beginners should start with simple, install-it-yourself options from solar dealers, focusing on ease of setup and 12V compatibility. Professionals plan expansion, selecting higher-wattage panels and scalable configurations to power larger loads. For a beginner, a basic Sunshine 100W panel kit or a couple of 100W modules can meet daytime needs, while a pro may mix 150W or 160W panels for bigger setups and future growth.

Ensure the mounting system fits your roof or rack and is weatherproof; use compatible connectors such as MC4 and verify the panel voltage matches your charge controller and inverter. Clean panels with a soft brush and mild soapy water, and avoid harsh chemicals. Look for proper certifications and a clear warranty from the brand you buy from.

Seek long-term performance warranties and recognized safety certifications; reputable brands like Sunshine, DP, and Qasa typically offer strong coverage and IEC/UL certifications. Understand what the warranty covers—panel performance, workmanship, and connectors—and how to claim service through the dealer.

Ask about your daily energy consumption, expansion options, and compatibility with existing batteries or inverters. Inquire about installation support, return policies, and after-sales service. Also request details on warranties, and how to add more Sunshine or DP panels later if your needs grow.
