We promise accurate quotes that don’t change, and offer an on time service guarantee, with exceptional communication. Our company is committed to being as environmentally friendly as possible by utilizing multiple donation and recycling centers.
"Everything went very smoothly. Sam, the plumber, and is highly professional and knowledgeable. He replaced 3 faucets, 2 sink plugs, two valves, and two supply lines. Sam inspected the p traps, and he added adhesive where it was necessary. Sam also took a look at my two year old hot water heater, and he assessed my water supply to this unit. We discussed performing a complete drain, and check of the components of the heater at a later date. Sam also advised me that a toilet in the basement should be replaced with a more updated commode. We rarely use this toilet, but it's 35 years old. I felt comfortable speaking with Sam. I did not sense he was doing a sales pitch."

Len The Plumber, LLC. is a leading plumbing and drain company serving Central Maryland. Our certified professional plumbers are available same day to assist residential customers in Anne Arundel County, Baltimore City, Baltimore County, Carroll County, Cecil County, Harford County, and Howard County. Our knowledgeable plumbers have years of experience dealing with a wide variety of plumbing issues including plumbing repairs, drain cleaning, water heaters, well systems, heating systems, sewer, water, and gas lines. We’re open 7 days a week with no extra charge on evenings or weekends!
"I am writing to express my deep dissatisfaction with the recent plumbing service I received from Len the Plumber. I paid nearly $300 for a technician to come out for 5 minutes, put a snake in the drain and leave.., yet it is now going on day three and the problem still has not been fixed. Two techs have been out to my home. I find this completely unacceptable. When a customer pays for professional service, they should not be left without a functioning toilet for days. I hoped for timely, effective, and professional service, and unfortunately, that has not been my experience. I hope this feedback is taken seriously, as this level of service does not reflect the reputation your company advertises. I hope for a prompt resolution to this matter. Thank you.

We are a full service, owner operated solar company headquartered in Eldersburg, Maryland. We design and install custom solar electric and back up battery systems for homes and businesses in Frederick, Carroll, Baltimore, Montgomery, Howard, Prince George's, Anne Arundel, and Washington counties. We do not provide service to existing systems that were installed by another company.
"I recently had a solar system installed by Celestial Solar Innovations and couldn't be happier with the experience. From the start, Jim was fantastic to work with—professional, knowledgeable, and clearly passionate about what he does. He took the time to walk me through every step of the process, explained the technology in detail, and answered all my questions thoroughly and quickly. I really appreciated his transparency and how he shared insights from past projects, clearly demonstrating a commitment to continuous improvement. The installation crew was just as impressive—friendly, professional, and attentive to my preferences. They took the time to talk with me during the install and followed my requests for conduit placement exactly. The equipment they use is top-notch and looks great on my home. Best of all, they managed all the coordination with my HOA, the power company and SRECtrade, so I didn’t have to lift a finger. While I received similar quotes from larger regional installers, I'm so glad I chose this local company. The personal attention and quality of work really stood out. I’ve already recommended Celestial Solar to friends and neighbors and will continue to do so. Highly recommended!"

Solar panels are fairly low-maintenance, but they do need occasional attention. A quick wash a couple of times a year and a yearly professional inspection help maintain efficiency. Watch for cracked glass, loose wiring, or hail damage; small fixes cost far less than waiting until output drops. If a panel is badly shattered, replacement—handled by a licensed pro—is often the smarter call.
Most panels last 25 to 50 years, so replacement is rare. Swap them out only when output drops noticeably, the warranty has run its course, or storm damage makes repairs impractical. Track your production data; if efficiency continues to slip even after minor fixes, it’s time to consult a solar installation professional and consider replacing a panel.
Homeowners are accountable for solar panel repairs unless their system is under a leasing agreement. Warranty coverage may reduce repair expenses for specific components. Warranty protection covers repairs when panels fail due to installation errors or unexplained issues. However, if a unit cracks due to an impact, the homeowner is responsible.
Always contact your installer and review your warranty before initiating repairs. Many manufacturers offer warranties ranging from 10 to 20 years. Inverters have a 10-year warranty, panels carry a minimum five-year workmanship warranty, and the overall system is protected for 25 years.
