This analysis evaluates the cost, weight, and additional power generation potential of adding solar panels to the sides of the seastead. It also considers the impact of solar reflections from the ocean and pH values on panel efficiency.
Assuming modern, high-efficiency solar panels with a cost of $3-$5 per watt (depending on panel type and quality), the cost of solar panels for 300 sq. ft. will depend on panel size and efficiency. For example:
| Task | >Detail | >Value | >
|---|---|---|
| Panel Capacity | >300 sq. ft. x 150 W/sq. ft. (30,000 W) | $45,000 - $75,000 | >
| Weight | >30,000 W x 4.5 lbs/watt (lightweight panels) | 135,000 lbs | >
| Cost per Square Foot | >Total cost / 300 sq. ft. | $150 - $250/sq. ft. |
With 300 sq. ft. of solar panels and 6 hours of effective sun exposure per day, the seastead could generate between 9,000 Wh (9 kWh) and 15,000 Wh (15 kWh) of energy daily. This would supplement the existing solar on the roof and provide additional power for systems like LED lighting, water pumps, or small appliances on the seastead.
Solar panels on the sides could receive additional power from reflections off the ocean surface. However, the benefits are likely minimal due to:
