In Dallas, Texas, you can expect to pay about $2.39 per watt for a complete solar panel system, installation included. So, a standard 5 kW system might set you back roughly $11,936 before tapping into any incentives. Depending on choices like the size of the system and the type of equipment you go for, prices might vary between $10,146 and $13,726. But here’s the kicker: with the federal solar tax credit, you can slash that cost by 30%, making solar power a more budget-friendly option.
