"They showed up on time and did the repair quickly and professionally. Because this is the second time in five years that compressor capacitor failed (note another company did first repair) he recommended a compressor and capacitor life extender kit. Came up with great price. "

"I paid $62000 to have my roofs repaired - not cheap for a disabled person. Hopefully, thei dropping the ball is not because Im disabled. They removed but did not properly reattach my ATT line to detached garage. Also, there was a fluke rainstorm about 1-1/2 weeks ago and i heard a dripping sound in / near chimney. I complained and Brent Eikanas their contact promised to have supervisor here to check leak TODAY between 10-11 am and anchor the ATT connection like it was before they removed it. They no-showed AGAIN. I had to remind them of other items they needed to do to finish/using my payment as leverage - removing the old gutter all the way - they had only half-way removed it. I have photos and next winter will have to video and record leak in/near fireplace. I had to start documenting because phone call is useless. The workers left nails and some trash too and on Cinco de Mayo, their last day here, they did two structures in 4 hours,"

The physical construction phase typically requires two to four months following the receipt of all necessary approvals. At the same time, the entire development process from initial concept to operation generally spans three to five years. Factors affecting the timeline include site conditions, workforce size, and project scope. The majority of the development period involves securing regulatory approvals, completing environmental studies, and establishing utility interconnection agreements.
Developing a solar farm requires an average of $400,000 to $500,000 per acre for equipment and installation, excluding property acquisition expenses. Based on industry averages, a six-acre installation typically supports one megawatt of capacity, capable of powering roughly 164 homes. Project economics vary significantly depending on whether land must be purchased or leased, with substantial regional variations in property values.
A solar installation can generate an average of $14,000 to $40,000 annually per megawatt, with variations based on electricity rates and contract terms. Annual maintenance expenses of approximately $15,000 per megawatt must be factored into financial projections. Most facilities operate under long-term agreements spanning 15 to 25 years, providing revenue stability throughout the project lifecycle.
A 20-acre property can support a viable commercial solar installation. Based on industry averages, this area could accommodate approximately three to five megawatts of capacity, sufficient to power 600 to 1,000 residences. This scale falls within the commercial solar farm category, offering enough capacity to achieve reasonable economies of scale while remaining manageable for smaller developers or community-based projects.
