How Callidus Wholesale Supports Installers Amid Solar PV Price Changes

At Callidus Wholesale, we recognise that solar installers, like you, rely on accurate, up-to-date information to protect your profitability. So we always offer timely insights into price movements, stock availability, and future supply chain considerations. We help our customers stay ahead of market shifts rather than being caught off guard.

Before we get to the Solar PV Modules that we stock, here’s how we protect your profitability…

1. Market Intelligence & Updates

We understand what is likely to affect solar prices. Just as the price of twin and earth cable is influenced by copper and aluminium costs—exacerbated by post-COVID market fluctuations—solar panel prices are dictated by supply-demand dynamics and material costs.

So we continuously monitor global trends in solar pricing, manufacturer production rates, and commodity market shifts. By analysing these trends for installers we provide insights to help you make better purchasing decisions.

In fact, we predicted that solar PV modules would be increasing in price in 2025 due to China’s change in export tax rebate for solar products that came into force in December 2024. It’s these types of insights that help installers stay at the forefront of market changes and protect their profitability to increase revenue.

2. Stock Availability & Strategic Procurement

We work closely with selected manufacturers we have enduring partnerships with. This ensures a reliable stock of panels at stable prices. When manufacturers reduce output to influence pricing, shortages can emerge. By maintaining strong relationships with key suppliers, Callidus Wholesale ensures that our customers are never caught without the products they need.

3. Price Protection & Cost-Effective Supply

Wouldn’t it be great to get solar equipment at a great price even when the broader market experiences price hikes? We achieve this for you with bulk purchasing and strategic warehousing. This allows us to offer competitive pricing despite price increases. So installers who partner with us  lock in more predictable costs and avoid being squeezed by sudden price increases.

4. Consultation & Business Support

Ahh, the defining factor in how we run our wholesale business. We say we do solar right and service better. That’s because the best wholesalers do more than just supply products. So we provide direct support to installers. We help them price jobs accurately based on market trends and advise on optimal times to purchase stock to maximize margins. Solar done right, Service done better.
