"Jimmy showed up to my home during a time when my thermostat was not working. That issue was fixed. He sold me a services contract and told me when he returned to services the units, he will cover the pipes outdoors. I purchased the contract for twice per year maintenance. I scheduled with him for a specific date. Appointment was confirmed but Jimmy did not show. When I called, he it appears that he forgot my appointment and he rescheduled saying he could not work in the rain. He rescheduled for a few days after and one of his workers showed up (Carlos). The guy showed up looking like he was someone who does not want to work and unprepared. So, I asked him if he has filters and he said know. Jimmy's workman did not bring filter, so I offered him filters I had stored. I asked him if he bought things to cover the pipes at the back, he said no. I called and left a message for Jimmy. Carlos was so rude and unprofessional. I was so scared of him and the way he was behaving. Carlos then said he would NOT do any service. IT WAS A WASTE OF MY TIME. He did return my money. BUT I will not recommend him. Will NOT use him again. As woman I will not hire again. Customer services was poor, reliability and punctuality poor."

"🚨 Avoid Len the Plumber – Negligent & Unsafe! 🚨 I hired Len the Plumber to install a brand-new water heater, but it failed after two weeks. They promised quick service but left us without hot water for days. Worse, the first technician concealed a serious fire hazard—the heater’s electrical components had actually caught FIRE and burned! A second technician finally admitted the fire risk, meaning my family could have been in grave danger. This is pure negligence and completely unacceptable. They replaced the heater but only after multiple delays, zero accountability, and putting our safety at risk. 🚫 DO NOT trust this company with your home’s safety! 🚫"

FAQs for solar panel installation projects in Upper Marlboro, MD
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.
