DIY Solar: Slash Costs with Craftstrom & Glass Panels

When it comes to setting up a DIY solar system, there's a trick to cutting costs without sacrificing performance: combining the best of plug-and-play kits with readily available, cheaper components. I put this idea to the test with Craftstrom Solar's system, and the results were eye-opening.

Disclosure: Craftstrom sent this unit for testing. All opinions and test results are my own.

What I Built

I started with the core Craftstrom Solar system, which includes the inverters and smart power meter. Instead of using their lightweight, flexible solar panels, I opted for rigid glass panels. For the first test, I used two 200-watt Calsun bifacial solar panels, which I connected in parallel to a single Craftstrom microinverter, for a total of 400 watts. These were initially just laid flat on the ground. Later, I also tested a single 405-watt residential-grade panel on a dedicated stand. The goal was to see if these more affordable, heavier panels could integrate seamlessly with the Craftstrom system and how much could be saved.

Why It Works

The beauty of the Craftstrom system is its modularity. The microinverters convert DC power from any connected solar panels into AC power for your home. As long as the panels' open-circuit voltage (VOC) is under 60V, the inverters can't tell the difference between lightweight flexible panels and heavier rigid glass panels. DC power is DC power. This means you can source panels from various places, including online retailers like Amazon or local suppliers, potentially saving a significant amount on the panels themselves. The Craftstrom power meter then intelligently manages the power flow, sending it to your home circuits and reducing your grid draw.

Parts & Specs

• Craftstrom Solar Microinverters: Designed for easy plug-and-play integration.
• Craftstrom Smart Power Meter: Monitors and manages energy flow.
• Calsun 200W Bifacial Solar Panels: Two units tested, available on Amazon.
• Residential 405W Solar Panel: One unit tested, sourced from a local supplier (Pay Off Solar in Utah).
• Powered Portable Solar Stands: Optional telescoping stands with adjustable angle, tie-downs, and stakes.

Math & Run-Time Numbers

My haphazard setup with the Craftstrom system (including other panels not explicitly detailed but contributing to the total) was producing 477.0 watts of electricity. My household consumption was 1.4 kW, with the remaining 900.0 watts drawn from the grid. On Phase 1, I was pulling 90W, and on Phase 2, 810W, with Phase 3 at 0W. This shows the system effectively offset a portion of my home's energy needs.

Here's a breakdown of current pricing (as of video publication, prices may vary and do not include coupon codes, taxes, or shipping unless noted):

• 400W Craftstrom Solar Panels (no stands): $524.00
• 400W Craftstrom Solar Panels + Racks: $633.99
• 400W Calsun Solar Panels (Amazon): $309.99
• 400W Calsun Solar Panels + 2 Powered Portable Solar Stands: $589.79
• 405W Pay Off Solar Panel (local pickup): $99.00
• 405W Pay Off Solar Panel + 1 Powered Portable Solar Stand: $238.99
• 800W Craftstrom Solar Full Kit (includes everything): $2,031.00
• Craftstrom Solar Kit Components (2 Inverters, Cables, 1 Power Meter) without panels: $1,060.00

To build an 800W system by buying Craftstrom components and sourcing panels separately:

• With two 405W Pay Off Solar Panels: $1,060.00 (Craftstrom parts) + $198.00 (2x $99 panels) = $1,258.00
• With four 200W Calsun Solar Panels: $1,060.00 (Craftstrom parts) + $619.98 (2x $309.99 panel pairs) = $1,679.98

Both DIY options offer substantial savings compared to the full 800W Craftstrom kit, especially with local panel pickup.

Pros & Cons

Pros:

• Significantly reduces upfront costs by sourcing rigid panels separately.
• Allows for greater power output per dollar invested, especially with local pickup deals.
• Stands elevate panels, improving snow shedding and preventing shading from ground cover.
• Adjustable stands allow for optimal sun angle throughout the day/season.

Cons:

• Rigid glass panels are heavier and less portable than Craftstrom's flexible panels.
• Rigid panels don't have integrated mounting points for the Craftstrom inverters, requiring DIY solutions or external stands.
• The Craftstrom inverter's magnetic antenna won't stick to aluminum-framed rigid panels, necessitating alternative mounting.
• Laying panels flat on the ground can lead to reduced performance due to shading from grass, leaves, or snow.
• Stands add to the cost, eating into potential savings.

When To Use This vs. Alternatives

This hybrid DIY approach is ideal for homeowners and tinkerers who are comfortable with a bit more hands-on work and want to maximize their return on investment. If you have a sunny yard and don't need to move your panels frequently, or if you can find great local deals on rigid panels, this is a strong contender. The Powered Portable Solar stands are excellent for ensuring optimal panel angle and mitigating ground-level shading, though they do add to the overall cost.

If you prioritize extreme portability, a truly plug-and-play experience, or need a lightweight solution for a balcony or RV, the full Craftstrom kit with their flexible panels is an excellent choice. Their panels are designed for ease of use, with integrated stands and magnetic properties for accessories.

Bottom Line

The Craftstrom Solar system works great with standard rigid glass panels, offering a compelling pathway to energy independence at a lower cost. While you'll need to address mounting the inverters and antennas yourself, the savings on panels, especially if sourced locally, can be substantial. For those willing to put in a little extra DIY effort, this hack makes grid-tie solar more accessible than ever.
