With a stellar rating of 4.9 based on 118 reviews, Renew Solar of Tennessee LLC is highly praised for its exceptional customer service and expertise in solar installation. Many reviewers commend the company's thorough approach and professionalism. This business is best for homeowners seeking a reliable and experienced installer. However, it may be slightly pricier than some competitors.
Akino Solar, also rated 4.9 with 118 reviews, stands out for its competitive pricing and high-quality service. Customers appreciate the knowledgeable staff and efficient installation process. It's a great choice for those looking for value without compromising on quality. The only downside is its relatively new presence in the market, which leaves some uncertainty about long-term reliability.
Your Home Solar boasts a 4.9 rating from 85 reviews, highlighting its dedication to customer satisfaction and quality installations. Clients often mention the timely service and professional team. This company is best for homeowners who prioritize customer care and quick turnarounds. However, its lower review count compared to the top contenders may raise questions about its long-term reliability.
Appalachian Renewable Resources has achieved a perfect 5.0 rating from 6 reviews, which speaks to its exceptional service and expertise. Customers appreciate the company's attention to detail and personalized approach. Best for those seeking a tailored solar solution, the main drawback is its limited review base, making it promising but unproven.
Sunrise Solar Solutions LLC has a rating of 4.4 based on 14 reviews, highlighting its solid performance and customer service. Clients appreciate the company's friendly staff and willingness to answer questions. This business is best for those who value a supportive experience. However, the limited number of reviews may indicate less experience in the market.
Efficient Energy of Tennessee boasts a perfect rating of 5.0 from a single review, showcasing its potential for high-quality service. The client praised the installation process and professionalism. While this business shows promise, its thin review base makes it unproven in the competitive solar market. The review base is still thin, so we read the rating as promising rather than proven and weighted it accordingly. Most of what reviewers hire it for is potential high-quality service. It serves Knoxville region, with $10,000 to $20,000 pricing, and the honest trade-offs are thin review base.
Sun Electric Co has a rating of 3.9 from 10 reviews, indicating a decent level of service. Customers note the company's reliability and decent installation work. This installer is best for those looking for a basic installation service. However, the lower rating and thin review base suggest that it may not be the best choice for all homeowners.
Solar Alliance has a rating of 3.7 based on 28 reviews, reflecting a mixed level of service. Some customers appreciate the competitive pricing, while others have noted issues with communication. Best for budget-conscious homeowners, the downside is that the mixed reviews might be a concern for those seeking consistent quality.
Design 1 Solar Group Knoxville has a low score of 2.3 from 11 reviews, indicating significant room for improvement. Customers have expressed dissatisfaction with service quality and communication. This business is best for those willing to take a chance, but the overall feedback suggests that many homeowners may want to explore more reputable options.
