We assess your site, roof structure, and energy usage to identify the most efficient and cost-effective system.
You’ll receive a tailored proposal outlining layout designs, projected generation, savings, NPV analysis and payback period.
Choose between full ownership, financed purchase, or a zero-CAPEX PPA, whichever best suits your business.
Our accredited engineers install and commission your system to MCS and NICEIC standards, ensuring minimal disruption.
We connect you to a live monitoring platform and provide ongoing performance tracking, maintenance, and support.
As a guide, a 100 kWp system requires around 500–600 m² of usable roof space. The exact size depends on panel efficiency, roof orientation, and shading. Our survey team will calculate the ideal setup during your feasibility assessment.
Yes. Solar can be installed on leased or rented properties through a range of options — including PPA, finance, or direct purchase. What's key is having the landlord’s consent and ensuring the structural suitability of the building. Altum supports you through the entire process, including liaising with the landlord to handle all technical and legal considerations.
A PPA allows your business to access solar energy with zero upfront cost. One of our trusted partners funds the installation, owns and maintains the system, and you buy the energy it produces at a lower fixed rate than your existing supplier, guaranteeing immediate savings and long-term price stability.
For purchased systems, the typical payback period is 3–6 years, depending on your energy usage, site conditions, and tariff rates. PPAs deliver savings from day one with no CAPEX involved.
Solar PV systems require minimal maintenance. Altum provides regular performance monitoring, cleaning, and scheduled inspections to ensure maximum efficiency and system longevity.
