After many hours of reading, & speaking to several solar installers, I chose O'Brien Electrical & Solar (Ahlec) , & am very happy with all aspects of the process. My (many!) questions were answered, quotation & advice were clearly explained, & presented for easy review. The installation team was punctual, polite, friendly, tidy, & happy to answer any questions. Any emails I sent were promptly answered, & a follow-up visit ensured I understood the app.
